中文摘要:
      首先给大滞后系统加人滞后时间削弱器,将大滞后的对象演变成小滞后的对象,然后基于模糊控制原理、极小值原理和PID控制理论,设计一种最优模糊PID控制器对小滞后对象进行自适应控制.仿真结果表明,加入滞后时间削弱器能使大滞后系统更容易控制;最优模糊PID控制器比模糊PID控制器具有更好的抗干扰性和鲁棒性,且系统响应的上升时间和调节时间明显缩短.
英文摘要:
      By adding a decreasing time delay controller into the large time delay system,the large time delay plant was changed into a small time delay plant.And then,by using the theories of fuzzy control,minimum control and PID control,an optimal fuzzy PID controller was designed to control the small time delay plant self-adaptively.The result of simulation has demonstrated that after adding the decreasing time delay controller,the large time delay system is easier to control;the optimal fuzzy PID controller has better ability of anti-disturbance and robustness than the fuzzy PID controller.At the same time,the rise time and setting time of the entire system's output response are both evidently shorter.
