摘　　要：针对一类具有不确定性和外部干扰的线性系统,基于模糊滑模控制原理,提出了一种基于阿克曼公式模糊切换增益调节的滑模控制器的设计方法;使用了一种新的方法设计滑模面,使系统在趋近切换平面的过程中始终跟踪理想的趋近过程,提高系统的位置跟踪精度;将该方法用于交流伺服控制系统位置控制器的设计,对该控制算法进行了稳定性分析,并进行了建模与仿真;通过选择合理的切换矢量C,使系统在趋近滑模平面的过程中始终跟踪理想的趋近过程,快速到达滑模平面;结果表明系统具有较强的鲁棒性和较快的收敛速度,验证了该方案的有效性。Considering a class of uncertain and disturbance linear system, basing on the theory of sliding mode fuzzy control, a design method of switch Gain Fuzzy Modulation of the sliding mode control based on Ackermann＇s formula is proposed. Using a new method to design sliding plane, so that the system approaches the process of switching plane is always closer to the ideal process of tracking and improving the accuracy of position tracking. The proposed approach is applied for designing a position controller for AC servo control System, analyze the stability of the control algorithm, establish the model and simulate the control algorithm. By selecting a reasonable switching vector C, the reaching process can be controlled to keep in tracing an ideal process of a reference model so that the system can reach the sliding mode quickly and precisely. Simulation results show that the system has strong robustness and high convergence speed. The validity of this method is proved.
