| 摘 要： | 以直流PWM伺服系统为对象,在建立数学模型基础上,从变结构控制理论出发,结合模糊控制的优点,设计了一种新型模糊变结构控制器,即在误差较大时采用滑模变结构控制,充分利用其响应速度快的特点,在误差较小时改用增量式模糊控制,并进行分级处理,以减弱抖振,提高控制精度,改善系统的动态性能。理论分析与仿真结果证明,该系统响应快、抖振小、鲁棒性较强,能够获得良好的控制效果。

| Abstract: | A new type of fuzzy variable structure controller (FVSC) has been designed for DC PWM Servo system, based on its mathematical model and the theory of variable structure control (VSC). The sliding-mode variable structure controller is adopted when the error is smaller and the incremental fuzzy controller is adopted with stage treatment when the error is bigger. The theory analysis and simulation results prove that the system has rapid response, little vibration and better robustness. |
