摘要

The heat exchanger and air-conditioning space in the central air-conditioning system are modeled in mathematic.Based on the models, we propose a cascade control strategy for temperature control of air-conditioning system.The setpoint response controller in the cascade control system is designed in terms of the robust control H2 optimal performance specification.According to the system operation requirement for disturbance rejection, a closed-loop for rejecting disturbance signals is configured and the controller in internal loop is figured out by proposing the desired closed-loop complementary function.Finally, the three controllers, the designed cascade control, traditional cascade P1D control and single PID control are simulated in central air-conditioning system.It is found that the setpoint response, the disturbance rejection, the robust and the performance of the designed cascade control system are better.
