| 摘 要： | 对于具有非线性、时变特性和纯滞后等特点的不确定系统,传统的PID控制和单纯的模糊控制都难以达到所期望的效果.无撞击切换模糊PID双重控制吸取了两者的优点,减少了模型切换时所产生的跳跃,既不依赖于对象精确的数学模型,又具有鲁棒性较强等优点.仿真结果表明,采用无撞击切换模糊PID双重控制保证了系统的快速和稳态性能好.

| Abstract: | For an uncertain system with nonlinear,time varying behavior and delay characteristic,it is hard to obtain optimal parameters by using the traditional PID controller and fuzzy logic control.Therefore,the Bumpless Transfer fuzzy PID dual mode control system is proposed,which is independent of mathematical model,and has the characteristics of robustness.The simulation results indicated that the Bumpless Transfer fuzzy PID dual mode control can ensure the speediness and stability of the system. |
