“…Permanent-magnet synchronous motor (PMSM) is widely used in modern industrials due to its attractive advantages, such as fast response, high efficiency, wide speed regulation range and low maintenance cost [1][2][3]. The PMSM drive system is essentially a nonlinear system subjected to model uncertainties and unknown load torque.…”

The output feedback position tracking control of permanent-magnet synchronous motor (PMSM) drive system is addressed in this paper. In order to obtain a differentiable disturbance theoretically, a continuous differentiable model is employed to model the nonlinear friction, and the desired velocity, rather than the measured or estimated velocity, is used in the friction compensation. Then, based on the desired friction compensation model, the reaching law based sliding mode controller is designed to make the position tracking error as small as possible in the presence of model uncertainties and load disturbance, and the gain of the reaching law is online tuned to adapt the variations of the controlled system. Moreover, a nonlinear extended state observer (NESO) is designed to simultaneously estimate the unmeasured states and unknown disturbance to guarantee the finite time stability of the proposed controller, and the designed NESO is proven to be exponentially stable and has zero estimation errors theoretically. Simulations and experimental results are given to verify the effectiveness of the proposed control scheme.

“…A novel speed controller was designed by the nonsingular terminal SMC with a disturbance observer for the velocity control of PMSMs [20]. In some researches [21,22], an adaptive SMC was designed for the speed and current control of PMSMs. In another research [23], a new exponential reaching law of the SMC strategy was proposed to improve the performance of the control of PMSMs.…”

A novel sliding mode controller (SMC) with nonlinear fractional order PID sliding surface based on a novel extended state observer for the speed operation of a surface-mounted permanent magnet synchronous motor (SPMSM) is proposed in this paper. First, a new smooth and derivable nonlinear function with improved continuity and derivative is designed to replace the traditional nonderivable nonlinear function of the nonlinear state error feedback control law. Then, a nonlinear fractional order PID sliding mode controller is proposed on the basis of the fractional order PID sliding surface with the combination of the novel nonlinear state error feedback control law to improve dynamic performance, static performance, and robustness of the system. Furthermore, a novel extended state observer is designed based on the new nonlinear function to achieve dynamic feedback compensation for external disturbances. Stability of the system is proved based on the Lyapunov stability theorem. The corresponding comparative simulation results demonstrate that the proposed composite control algorithm displays good stability, dynamic properties, and strong robustness against external disturbances.

“…To achieve an accurate control of the motor, the disturbances should be accurately estimated and compensated. There are many observers for disturbances estimation, such as unknown input observer [16], disturbance observer [17,18], extended-state observer [19][20][21]. The applications of the observer for PMSM drive systems are presented in [18,19].…”

To enhance the control performance of permanent-magnet synchronous motor (PMSM) drive systems, achieving high-precision motion control, a generalized predictive control (GPC) method based on a novel extended-state observer (ESO) is investigated for the speed control of PMSM. In this paper, the controller design consists of two steps. Firstly, according to the continuous time model of PMSM, using the Taylor series expansion, the predictive value of motor speed in finite time is derived, and the single-loop speed controller by combining the speed loop and q - axis current loop is obtained through the defined cost function. The structure of the controller is simple compared to other forms. Secondly, considering the uncertainty of the load torque and the model uncertainties, a novel extended-state observer is designed to compute the actual torque, and the observed value is introduced to the GPC controller. The simulation and experimental results show that the proposed GPC+ESO control method has superior dynamic performance and strong robustness.
