基于遗传算法的PID参数优化方法

PID参数整定与优化一直是自动控制领域研究的重要问题，采用遗传算法进行PID参数优化是一种寻求全局最优且与初始条件无关的优化方法，在参数优化过程中，考虑了2种不同的目标函数做了大量仿真实验。仿真结果表明了遗传算法应用于控制器参数优化的可行性和有效性，不失为一种具有较好实用价值的PID参数优化方法。

Optimization of PID parameters based on genetic algorithm

The setting and optimization of PID parameters are always the important stady topics in the automatic control field.To carry out optimization of PID parameters by using genetic algorithm is a kind of optimization method to explore the overall optimum and independent of the initial conditions.In the optimizing process,a number of simulating experiments were conducted with two dif-ferent target functions taken into consideration.The simulation results show that,to apply genetic algorithm to the feasibility and ef-fectiveness of optimization of controller's parameters is a good practical optimization method of PID parameters.
