“…Fuzzy adaptive PID control takes error signal and differential signal of error signal as input signal of controller, and establishes fuzzy rule table based on the influence of proportion, integral and differential signal on control effect, and modifies PID controller parameters through fuzzy rules and input signal value. Some scholars also proposed that the use of synovial membrane control is to replace the PI controller of the outer speed loop in the vector control system [9,10]. The synovial membrane control is designed to switch the hyperplane of the system so that the control system continuously changes the control structure based on different states, makes the system move according to the state trajectory of the predetermined 'sliding mode', and considering that the characteristics and parameters of the system only depend on the designed switching hyperplane and have nothing to do with external interference, the control method is robust.…”

In this paper, an improved auto disturbance rejection controller (ADRC) is applied to permanent magnet synchronous motor (PMSM) speed control system. Specifically, the improved ADRC is proposed to solve the defect that the nonlinear function of traditional ADRC is not differentiable at the piecewise point. In addition, considering that there are numerous parameters to be optimized in ADRC, an improved moth-flame optimization (MFO) is proposed to obtain ADRC parameters, and adaptive inertia weight coefficient and optimization mechanism based on the fusion of refraction operation and chaotic search are proposed to improve the convergence speed and optimization accuracy for MFO. Simulation and experimental results show that the improvement strategies proposed in this paper can increase the optimization performance for MFO algorithm effectively so that obtained more appropriative ADRC parameters. The improved ADRC can effectively improve the tracking control performance of PMSM speed control system.

“…Several control strategies based on conventional controllers, such as proportional-integral (PI) control [5,6] have attracted attention owing to their simplicity and ease of implementation on hardware; however, they are highly dependent on actual drive parameters and require exact parameter values to tune the PI gain to achieve efficient closed-loop performance. To eliminate the parameter dependency on the control design, nonlinear controllers have been developed [7][8][9][10][11][12][13][14]. In previous research [7][8][9], deadbeat control showed excellent speed tracking performance, but it depends highly on the IPMSM parameters to achieve efficient tracking performance by setting the closed-loop poles to zero.…”

“…However, this control scheme depends highly on gains and requires extensive knowledge to choose appropriate fuzzy interference rules to achieve excellent speed tracking. Model predictive control (MPC) [12][13][14] is easy to implement and straightforward, but highly depends on the exact model of the IPMSM to predict the future control output variables that ensure adequate closed-loop control effects.…”

The speed response of the interior permanent magnet synchronous motor (IPMSM) drive at low speeds was analyzed. To eliminate the effect of external disturbance or parameter uncertainty, a nonlinear speed control loop was designed based on the sliding-mode exponential reaching law, which reduces chatter, which is the major drawback of the constant reaching law sliding-mode control technique. The proposed nonlinear speed control eliminates speed ripples at low speed under load disturbance. The problem of speed convergence at low speed is caused by electromagnetic torque ripples, which cause shaft speed oscillations that affect drive performance. The main objective of the proposed method is to change the traditional IPMSM control design by compensating with an appropriate signal along the reference current and across the output of the speed control loop. To optimize the speed tracking performance during disturbances or parametric variations, a nonlinear speed control scheme is designed that can vigorously adapt to the change in the controlled system. The comparative analysis shows that the method provides excellent transient performance (e.g., fast convergence response, less overshoot, and fast settling time) and standstill performance (e.g., reduced steady-state error) compared with conventional control methods at low speed under varying load conditions. The method is easy to implement and does not require additional computational cost. To demonstrate the effectiveness and feasibility of the design approach, a numerical analysis was conducted, and the control scheme was verified using MATLAB/Simulink considering various operating conditions.

A new formulation of the direct speed control (DSC) method for permanent magnet synchronous motor (PMSM) is proposed. The proposed DSC method employs a direct voltage control to synthesise the d and q axes stator voltage. In this method, no q-axis current loop regulation is required. Thus, a new concept of the dynamic limiter (DL) is proposed to limit the undesirable current rises. The mathematical analyses, frequency and time domain simulations, and experimental test results highlight the simplicity and effectiveness of the proposed DSC method. Furthermore, sensorless operation of the method can make it a reliable alternative for low-cost drive of PMSM.
