摘要
介绍一种用组合控制器控制的交流传动系统，该系统综合利用模糊控制和PID控制的优点，来提高系统的动态和稳态性能。利用状态观测器修正因系统参数变化及系统的非线性造成的控制误差，引入正交试验法进行参数整定，采用平滑方式实现两种控制的切换。仿真结果表明系统性能优良，并具有实时性强，便于实现等特点。
In this paper, a combinatory controller used in an AC drive system is introduced. The advantage of combinatory controller is used to improve the system's performance in dynamic and steady characteristic. The state recognizer is used to rectify the variations of system's parameters and the system nonlinear. The right-across experiment method is introduced to adjust the parameters. A smoothing method is used to control the exchange between the two controllers. The result of emulation indicates that the performance of system is excellent, with good real time character and easy to realize.
