【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。更多还原

【Abstract】 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 decoupling 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.更多还原
