PID Controller Design Based on Genetic Algorithms for Twin Rotor MIMO System

双旋翼多输入多输出系统是一套具有复杂非线性和强交叉耦合性的控制系统实验装置,难以进行控制参数的整定。而遗传算法对问题的依赖性小,适合复杂非线性系统的参数寻优。文中利用遗传算法,借助Matlab语言和Simulink仿真模型,实现了双旋翼多输入多输出系统PID控制器的设计。仿真结果表明,该控制器是有效的。

Twin rotor MIMO system is a laboratory set-up which has complex nonlinearity and significant crosscouplings.These features make it difficult to optimize its controls parameters.Genetic algorithms relies little on system, it is capable of parameter optimization of the complex nonlinear systems. By using the genetic algorithms and Matlab programming language,as well as the Simulink model,this paper carried out the design of the PID controller for the twin rotor MIMO system. The results of the simulation show that the controller is efficient.
