摘要
文章以某房间的中央空调温度控制系统为研究对象,针对该控制对象的非线性、大迟延的动态响应特性,设计了具有一定自适应能力的免疫PID控制器,并与Smith控制器相结合,来消除其延迟时间。通过matlab仿真结果表明,这种控制方法与常规PID控制方法相比较,可以缩短调节时间、提高控制系统的稳定性,具有更好的动态调节特性。
The research object is the central air conditioning temperature control system in this paper.Because the control object is the non-linear and large delay dynamic response, we design an immune PID controller with adaptive ability and combine with Smith controller to to eliminate its delay time. The Matlab simulation results show that compared with the conventional PID controller, it can shorten the adjustment time, improve the stability of the control system, and have better dynamic regulation characteristics.
