CMAC and PID Compound Control in Air Conditioning Systems

Considering the multi-variable, nonlinearity, time lag and time variation characters of air conditioning systems, it is difficult for traditional Proportional Integral Derivative (PID) control to get good control performance.A compound control strategy based on cerebellar model articulation controller (CMAC) and PID controller is used to the system. Obtained results show that the compound control algorithm can improve the precision of control, the speed of responding, and has better dynamic and steady-state characteristics.
