摘　　要：针对控制器参数在线优化难题,提出了一种基于免疫原理的控制器参数优化整定方法。该方法借助生物免疫原理,将控制器参数整定的最优解和可行解各自抽象为抗原与抗体,采用免疫遗传算法,在满足约束条件下求解出使目标函数J(x)为极值时所对应的控制器参数。论述了设计步骤,描述了参数优化过程,对算法作了仿真比较研究,给出了仿真实验结果,分析了系统性能指标。仿真实验结果显示出了该方法的优势,验证了该方法的合理性与有效性。仿真研究结果表明所提出方法可用于解决复杂控制系统的参数整定。Aimed at the puzzle of optimization on line for controller parameter, the paper proposed a sort of tuning method in parameter optimization for controller based on the immune theory. By means of immunobiologic principle, the method took respectively the optimum solution and feasi- ble solution of parameter tuning for controller to be abstracted as the antigen and antibody, by use of immune genetic algorithm, under the condition of satisfying constraint, it solved the corre- sponding controller parameter that made the objective function J（x） get the extremum. In the pa- per, it expounded the design step, described the optimization process of parameter, made the comparative research of control algorithm, gave the results of simulation experiment, and ana- lyzed the performance index of system. The simulation results demonstrated the superiority of this algorithm, and validated the rationality and effectiveness. The research result shows that the proposed method can be applied to parameter tuning for solving complex control system.
