摘要
在交流位置伺服系统中,传统PID控制由于调节器参数固定,无法应对系统参数变化与扰动等方面的影响,系统鲁棒性较差。鉴于模糊控制不依赖于控制对象的数学模型,鲁棒性强等优点,将模糊PI控制策略同时引入到位置环与速度环调节器中,实现系统的双模糊PI调节器控制。通过仿真软件对该方案进行验证,并搭建实验平台进行测试。仿真和实验结果均表明,该方案相对于传统PI调节器控制而言定位更快并具有较小的转速脉动。
In the DC position servo system,the strategy of traditional PID control is unable to cope with the effects of the system parameter changing and disturbance with poor robustness for the controller parameters fixed. The Fuzzy PI control strategy was introduced to the position loop and speed loop controller to realize the double Fuzzy PI regulator control because of which the Fuzzy control isn′t dependent on the mathematical model of controlled object,robust,etc. The scheme was verified in the simulation software,and the experimental platform was set up for testing.The Simulation and experimental results indicate that the scheme is faster positioning and smaller speed pulsation compared with the traditional PI regulator control.
