摘　　要：提出了一种应用改进二进制差分进化算法(MBDE,modified binary differential evolution algorithm)对PI/PID控制器参数进行优化整定的方法。基于参数稳定域理论,预先确定保证闭环系统稳定的PI/PID控制器参数的约束范围。根据实际问题的需要,结合相应的性能指标,设计恰当的复合性能准则作为优化算法的优化目标,并采用MBDE智能优化算法对优化目标进行优化,从而得到PI/PID控制器的最优参数。将该方法分别应用于针对某循环流化床床温和一个非最小相位系统的PI/PID控制器的参数整定。仿真结果表明,通过上述方法设计的PI/PID控制器,跟传统方法相比,实现方式简单灵活,可以满足闭环系统动态性能的特殊需求。A method for tuning the parameters of PID controllers via modified binary differential evolution algorithm （MBDE） for general SISO systems, especially self-regulating systems, was proposed. The parameters stability region was predicted presumedly according to the parameters stability region theory. The MBDE algorithm was employed to tune the parameters of PID controllers combined with a certain performance index according to the practical applications. The range of parameters to be optimized was confirmed by the parameters stability region. The method was applied to control the bed temperature of a circular fluidized bed and a non-minimum phase system, respectively. The simulation results illustrate its validity and effectiveness.
