| 摘 要： | 分数阶比例-积分-微分(PID)控制器是一种把PID控制器的整数阶次推广到分数的比例、积分、微分控制器,它比传统的PID控制器更能精确地控制复杂的被控系统.而参数的取值对控制效果的好坏起着决定性作用,为此提出了一种混合粒子群算法BFA-PSO优化参数值.该算法将具有趋化、繁殖和驱散特点的细菌觅食算法和参数少,易于优化的粒子群算法相结合来计算出精确的分数阶PID控制器的参数值.通过对传统PID控制器和分数阶PID控制器参数优化的实验仿真,结果表明基于该算法的分数阶PID控制不仅无超调量、收敛速度快,而且鲁棒性强、收敛精度高,可用于控制不同的对象和过程.

| Abstract: | Fractional order Proportional-Integral-Derivative(PID)controller is a PID controller to the fractional Proportional-Integral-Derivative controller;it can more precisely control the complicated system than the traditional PID controller.The parameter values play a decisive role in the effects of control.A new hybrid algorithm was proposed.The Bacterial Foraging Algorithm and Particle Swarm Optimization(BFA-TPO)were combined to calculate the precise fractional order controller parameter values,which used the ... |
