摘要
针对目前能量回馈系统效率低的问题,提出一种基于改进的遗传PID(比例-积分-微分)算法对能量回馈系统进行控制.首先建立回馈制动的数学模型,然后根据其模型采用仿真软件(MATLAB),并结合改进的遗传PID算法进行仿真实验.实验结果表明,改进的遗传PID算法比传统PID算法控制效果更好,稳定性、鲁棒性及抗干扰能力更强,且回收效率提高了25.8%.
Aiming at the problem of low efficiency of energy feedback system,we proposed improved genetic PID(proportional-integral-derivative)algorithm to control an energy feedback system.First,the mathematical model of feedback braking was established.Then,according to the model,simulation software(MATLAB)combined with improved genetic PID algorithm was used to carry out the simulation experiment.The experimental results show that compared with the traditional PID algorithm,the improved genetic PID algorithm has better control effect,stronger stability,robustness and anti-interference ability,and the recovery efficiency is improved by 25.8%.
