“…The proposed fixed-time multi-faults estimation method is applied to the PMSM synchronization system described in the work by Dai et al (2022), and the system topology is shown in Figure 2.

“…In the PMSM synchronization system in the work by Dai et al (2022), each agent needs to obtain the information of neighborhood agents. Considering that the sensor faults will result in erroneous information being included in the information interacting between agents, thus the communication protocol designed in the work by Dai et al (2022) needs to be compensated using the estimated sensor fault information. The communication protocol with sensor faults information can be rewritten as…”

An integral sliding mode observer-based fixed-time multi-faults estimation method is proposed to solve the problem of fast fault estimation for a class of nonlinear systems with multiple types of faults simultaneously. First, a class of nonlinear systems with actuator and sensor faults is considered, and the original system is transformed into two subsystems through coordinate transformation to decouple the actuator and sensor faults. Then, intermediate variables are introduced to transform sensor faults into actuator faults of the augmented systems. For the transformed system, a fixed-time fault observer based on integral sliding mode is designed to realize the fast estimation of unknown terms, and the fixed-time convergence performance is proved. Moreover, based on the output of the fault observer, the actuator and sensor faults in the original system are reconstructed. Finally, the fault model of the permanent magnet synchronous motor is established in the hardware-in-the-loop platform, and the effectiveness of the designed fault estimation method is verified.

To further improve the fast and stability of indirect matrix converter- driven permanent magnet linear synchronous motor control system, a nonsingular fast terminal sliding mode control algorithm based on disturbance observer is proposed in this paper. First, to realize the fast and accurate tracking control of the position reference signal, a nonlinear fast terminal sliding mode is introduced; secondly, to reduce the effects of load perturbations and parameter variations on the control effect, a broad learning-based disturbance observer is designed for feedforward compensation of disturbances to make full use of the excellent nonlinear approximation capability of broad learning; finally, simulation models are built on the MATLAB/Simulink platform, and the results are verified by comparing with other control methods.

To further improve the fast and stability of the control system of an indirect matrix converter (IMC) driven permanent magnet linear synchronous motor (PMLSM), a nonsingular fast terminal sliding mode control (NFTSMC) algorithm based on the disturbance observer of stochastic configuration networks (SCNs) is proposed. The NFTSMC algorithm is used to design the outer loop controller, which can reduce the influence of the IMC by the power supply voltage and high-frequency harmonics generated by switching. To further reduce the disturbance of IMC-PMLSM during operation, in this paper, a nonlinear disturbance observer based on SCNs is constructed, which solves the drawback that the traditional disturbance observer needs to adjust the parameters frequently under different working conditions. Finally, a simulation model is established on the MATLAB/Simulink platform to verify the effectiveness and advantages of the proposed control method.
