内模控制(internal model control，IMC)因其结构简单、易于实现已得到广泛关注，但其控制性能与滤波器时间常数有直接关系，影响了其在高性能变频调速系统中的应用。该文提出了一种采用免疫算法的感应电机内模控制策略，以免疫应答系统为基础，引入一种免疫算法，分析了该算法的实现方式。将该免疫算法植入到内模控制器中，实现对滤波时间常数的在线调整，克服了内模控制器因滤波时间常数固定带来的系统动态性能不佳的问题。仿真与实验结果验证了采用免疫算法的感应电机内模控制策略的有效性。

The internal model control (IMC) has been widely attended because of its simple structure and easy realization, but its control performance has a relationship with the filter time constant directly, so that its application of high-performance is influenced in the variable frequency system. A novel method of the internal model control strategy of induction motors using the immune algorithm (IA) is proposed in this paper, and the immune algorithm is studied on the basis of the immune response system, and then the algorithm realization is analyzed. The immune algorithm is introduced into the internal model controller, and the filter time constant adjustment on-line is realized by taking full advantage of the adaptivity of the immune algorithm, and thus the problem that the system dynamic performance is not good because of the filter time constant of the internal model control can be overcome. The simulation and experimental results verify the effectiveness of the internal model control strategy of the induction motor using the immune algorithm.
