摘　　要：针对系统参数多变性和非线性的特点,采用串级模糊滑模控制策略,建立二次调节转速控制系统的数学模型。该控制策略充分结合了两种控制方法的优点。利用MATLAB软件进行仿真,并与串级PID控制仿真结果进行比较。结果表明,采用基于模糊自适应调节的滑模控制能够使系统具有更好的鲁棒性,系统的控制性能得到极大的提高,当系统参数发生变化时,能够保持较强的鲁棒性和抗干扰能力。A mathematic model of secondary regulation speed system was established based on cascade fuzzy sliding mode control strategy considering the parameter variability and nonliner characteristics of the system.This control strategy combined advantages of two control methods.The simulations of the system were made with MATLAB and the results were compared with those of cascade PID control.The results indicate that applying sliding mode control based on fuzzy self-adaptive adjusting has better robustness and the control performance of the system has been greatly improved,when the system parameters change,the system can maintain better robustness and anti-jamming ability.
