摘要
逆变电源控制系统具有非线性、时变性等性质,运用常规的模糊PID控制难以达到满意的控制效果。将专家经验用于模糊PID参数的在线自适应整定,设计了基于专家经验的自适应模糊PID控制器。这种控制器既具有模糊PID控制器的精度高、稳定性好、鲁棒性强的优点,又具有专家控制器进入稳定状态快的特点。仿真实验结果表明:基于专家经验的自适应模糊PID控制器在逆变电源控制系统的控制中,控制性能优于单独模糊PID控制的性能,表现出了良好的自适应性、稳定性、鲁棒性,能够用来实现对逆变电源控制系统的有效控制。
The control system of inverters has character of nonlinear and time varying and so on,the perfect control cannot be obtained with conventional fuzzy PID control method.In order to improve the performance of fuzzy PID controller in the control system,a self-adaptive fuzzy PID control based on expert＇s experience is applied.In this paper,the working principle of the whole system is provided,and the design process of fuzzy controller is also given in detail.Simulation results show that： the self-adaptive fuzzy controller can not only stabilize the output sine waveforms but also realize rapid transient response under parameter variations and load disturbances.Its control performance is better than conventional fuzzy PID controller.It can be used to control the control system of inverters effectively.
