Aiming at the problems of disturbance, coupling and fluctuation of load existing in permanent magnet synchronous motor (PMSM),which is used in the servo system of self-propelled gun, the auto disturbance rejection control technique (ADRC) is introduced into in the servo system of self-propelled gun. It can play with the best effect of the servo control system. The simulation results show that ADRC makes the servo system of self-propelled gun has better accuracy and robust.

Disturbance Rejection Control

In order to improve the rejection ability of the boat rocking disturbance and wind load disturbance on Ship-borne Servo Control System, the position linear ADRC (LADRC) is designed. First, mathematical model of Ship-borne Servo Control System is established, and PID control method is used for simulation. Methods used LADRC, estimated and compensated the wind disturbances and boats rocking disturbances, greatly. The simulation results show that ADRC method for active immunity, which greatly improves the immunity system and tracking accuracy, and the parameter adjustment is simple, just adjust a parameter can get good control performance.

This paper studies the ADRC(Active Disturbance Rejection Control) technique further used in Permanent Magnet Synchronous Motor. Combining the ADRC with the self-optimizing technique, we design a controller with Self-optimizing Control. The result of simulation shows that the ADRC technique with Self-optimizing Control has better control characteristics, compared with the classical PID and ADRC techniques.

In order to improve the performance of the servo control system driven by a permanent magnet synchronous motor (PMSM) under novel direct torque control (NDTC), which, utilizing composite active vectors, fixed sector division criterion, is proposed in this paper. The precondition of the accurate compensations of torque and flux errors is that the sector where the stator flux linkage is located can be determined accurately. Consequently, the adaptive sector division criterion is adopted in NDTC. However, the computation burden is inevitably increased with the using of the adaptive part. On the other hand, the main errors can be compensated through SV-DTC (DTC-utilizing single active vector), while another active vector applied in NDTC can only supply the auxiliary error compensation. The relationships of the two active vectors’ characteristics in NDTC are analyzed in this paper based on the active factor. Furthermore, the fixed sector division criterion is proposed for NDTC (FS-NDTC), which can classify the complexity of the control system. Additionally, the switching table for the selections of the two active vectors is designed. The effectiveness of the proposed FS-NDTC is verified through the experimental results on a 100-W PMSM drive system.

Disturbance Rejection Control

For optimal control of synchronous machine, chattering phenomenon will appear if traditional slider control is adopted because permanent magnet synchronous machine is a complex nonlinear time-dependent system with strong coupling of current and rotational speed to cause the deterioration of system control performance with load or load disturbance. In this article, based on the mathematical model of permanent magnet synchronous machine, a control system for it, which combines sliding mode control and active disturbance rejection control, is proposed to improve the dynamic performance and robustness of control system. In the control system, sliding mode control is adopted to control the inner current of machine and active disturbance rejection control is adopted to control the outer speed. The load disturbance of system is also estimated and offset. The results of matlab simulation show that the control system can eliminate serious chattering phenomenon existing in sliding mode control, improves the robustness of system for load and system parameter disturbance as well as has great dynamic and static performance.
