摘要
目前大滞后过程的控制问题仍然是公认的难题,并且许多被控过程都具有时变特性,即参数或结构随时间和环境的变化而改变,这更加大了控制的难度。通过深入分析仿人智能控制和模糊控制的优缺点,充分利用模糊控制不需要被控对象的数学模型、抗干扰能力强、鲁棒性好,和仿人智能控制抗滞后性强的优点,各取所长,提出了一种适合于时变大滞后过程的仿人智能模糊控制方案,并指出了其设计思路和步骤。仿真结果证明了该方案具有较好的动静态响应特性和较强的鲁棒性,为解决时变大滞后过程的控制问题提供了一种可行的方法。
Both the Human - emulated Intelligent Control and Fuzzy Control are analyzed in the paper, and a combined control law is proposed for time - varying processes with large time delay. Then the design procedure of HSIFC is pointed out. Simulation results show the proposed scheme has good dynamic and static responses, and strong ability in robustness.
