摘　　要：解耦一直是控制系统中比较难解决的实际问题,为了消除控制系统中耦合的成分,从一个实际的模型出发,通过建立系统模型的传递函数,利用多变量频率设计理论中静态解耦的思想,产生一个解耦器,从而消除系统中耦合的成分,使系统变成两个单输入单输出的模型,然后在此模型基础上,设计出一个解耦的PID控制器。仿真结果验证了该解耦器能够减少系统中耦合的成分,达到解耦的目的。该方法简单实用,可以推广到许多实际的耦合系统中。Decoupling is a difficult practical problem in controller design. In order to eliminate the coupling of systems, a decoupler is designed for a practical system model by building the transfer function of the model and utilizing the principle of static decoupling in multi-variable frequency design theory. This method eliminates the coupling elements of the system and turns the system into two SISO models, Then, a decoupiing PID controller is designed. Simulation results show that the decoupler is effective. The algorithm is easy to realize and can be expended to many practical coupling systems.
