Abstract ：
In this paper, a nonlinear servo control method based on finite-time observer is developed for position control of permanent magnet synchronous motor (PMSM). The nonlinear servo control law consists of two parts, where the linear part is responsible for the fast dynamic response and the nonlinear part is responsible for reducing the overshoot when the system approaches the steady state. To tackle the time-varying uncertainty occurring in the system, a finite-time extended state observer is proposed to estimate the lumped disturbance for feed-forward compensation in the control loop. Simulation and experimental results verify that the proposed control scheme can track the target position quickly and accurately, and is robust against disturbance and uncertainty. © 2024 Technical Committee on Control Theory, Chinese Association of Automation.

Abstract ：
With the increasing diversity of market entities in the integrated energy system (IES), the interests of multiple entities become complex and variable, leading to disorganized competition among entities in the trading market. Therefore, this paper presents an optimal operation strategy for IES employing a multi-game with tri-level transactions. Firstly, a tri-level IES framework is established with the energy production provider alliance, energy sales agent, and energy user agents as the main entities. Secondly, to handle the uncertainty of renewable energy, a MD-K2 dynamic bayesian network method describing the spatiotemporal correlation of wind and photovoltaic is proposed, and generates probabilistic scenarios. Then, a tri-level multi-game optimization operation model is constructed considering multi-dimensional transactions and demand responses, and is proved to achieve the game equilibrium. Finally, the tri-level model is converted into bi-level mixed-integer linear programming (BMILP) problem, which is solved by a bisection-based distributed iterative algorithm. The simulation results indicate that the optimization strategy improves the interests of tri-level entities and promotes fair distribution of cooperative benefits among alliance members.

Abstract ：
Equivalent circuit model (ECM) is a common method to simulate the electrochemical characteristics of lithium-ion batteries (LIBs). Fractional order model (FOM) has been proved to be able to characterize the internal characteristics of the battery more accurately, and the identification of model parameters is an important prerequisite to construct the ECM of LIBs. In this paper, a model parameter identification algorithm based on Beetle Antennae Search-Recursive Least Squares (BAS-RLS) is proposed for the FOM of LIBs. Firstly, the open circuit voltage (OCV) of battery is identified by Rint model. After obtaining the OCV of the battery, the BAS-RLS algorithm is used to identify the parameters of the FOM. The verification of four working conditions of LIBs confirms that the constructed FOM has higher accuracy. The maximum RMSE and MAE of the model output terminal voltage indexes under four working conditions are 9.1783 mv and 7.0939 mv respectively.

Abstract ：
This paper mainly studies the state of charge (SOC) estimation of lithium batteries based on a fractional-order adaptive square-root cubature Kalman filter (FO-ASRCKF). Firstly, a fractional-order model (FOM) of lithium battery is established by using fractional-order derivative theory. In order to meet the identification accuracy, an improved adaptive genetic algorithm is applied to the process of multi-parameter model identification. Then, the FO-ASRCKF algorithm based on FOM and adaptive rules is proposed, and a comparative experiment with Fractional-order adaptive iterative extended Kalman filter (FO-AIEKF) and Integer-order adaptive square-root cubature Kalman filter (IO-ASRCKF) is carried out. The experimental results show that the proposed FO- ASRCKF can work normally under various working conditions, and it has higher SOC estimation accuracy, with the mean absolute error (MAE) being less than 0.5%. Moreover, it can also overcome the divergence caused by noise and wrong initial values, indicating a better robustness.

Abstract ：
Accurate estimation of State of Charge (SOC) based on equivalent circuit model (ECM) of Lithium-ion batteries (LIBs) is an important research topic. Recent research has found that fractional-order model (FOM), as one kind of equivalent circuit model, can provide a better description of LIBs dynamics than the conventional integerorder ECMs. However, it is difficult to directly identify an FOM online. In this paper, a synergy of Beetle Antennae Search and Recursive Least Squares (BAS-RLS) is proposed to identify the parameters of an FOM for LIBs. Specifically, the BAS is adopted to determine the fractional order, while the remaining parameters of FOM are estimated via the well-established RLS algorithm. A comparison study will demonstrate that this method offers a similar modeling accuracy as the Particle Swarm Optimization (PSO), and the online estimated model is more accurate than offline estimated models. Based on the identified FOM, this article then explores the battery SOC estimation from two aspects: initial value effect of the SOC and the comparison of multiple estimation algorithms, thus verifying the advantage of the proposed method for LIBs modeling and SOC estimation.

Abstract ：
Incremental photoelectric encoders inevitably have undesirable factors such as quantization errors, manufacturing defects and wear and aging, which bring noise to the speed estimation. The previous speed measurement methods of motor rotors all use the differential method. The differential method amplifies the noise and introduces a time delay to the controller, which are extremely detrimental to the controller design. This article aims to use Nonlinear differential tracker (NDT) to estimate the rotor speed of a DC servo motor without increasing hardware resources, and to provide reliable speed feedback information for the controller. Given the rotor position information of the motor, this method can quickly track the derivative of the input position signal, avoiding the problem of noise amplification caused by other methods, and the algorithm is simple and easy to implement on a microprocessor. Simulation and experimental results verify that this method can effectively reduce noise interference and provide relatively smooth speed estimation information with less jitter. It is of great significance to the design of the control system. © 2022, The Author(s), under exclusive license to Springer Nature Singapore Pte Ltd.

Abstract ：
The advantages of switched reluctance motor(SRM) are obvious, and it applies to more and more industries. However, the torque ripple is more serious than other kinds of motors, so the control strategy of SRM is very important. As a kind of variable structure nonlinear control, sliding mode control is widely used. In this paper, the torque controller in indirect torque control(ITC) strategy is implemented with sliding mode control. Through the stability analysis of ideal conditions and parameter perturbation, the selection of controller parameters is given. Finally, the controller is verified by simulation and experiment. The simulation and experiment show that the controller can effectively track the real-time changing torque instruction, and the tracking effect is good. © 2022 IEEE.

Abstract ：
Torque ripple is an inherent property of switched reluctance motor (SRM), which seriously affects the control performance and application of the motor. This paper proposes two torque ripple suppression control strategies based on torque-sharing function (TSF). According to the symmetry characteristics of the flux linkage and rotor position curve family, a fourth-order Fourier series is used to fit the SRM flux linkage analytical model. The coefficient of each harmonic term of the flux linkage model is a function related to current, expressed by a sixth-order polynomial. The torque analytical formula can be derived from the flux linkage model. The torque error is calculated via the identified torque model and is compensated through TSF controller in order to reduce torque ripple. The torque model can also be used to establish the torque loop to achieve accurate tracking of the TSF reference torque to reduce torque ripple. Digital simulation was conducted, followed by the implementation on a SRM test bench using a 28335DSP as the master control chip. The experimental results are consistent with the simulation results, and indicate the effectiveness of the proposed schemes.
