Simulation Study on DMC Control of Water Outlet Temperature for Maglev Water Chiller
In response to the problem of time-lag and external interference in the control of the water outlet temperature of the maglev water chiller,and the poor performance of traditional PID control,a control and simulation model was established based on dynamic matrix control algorithm.By predicting and correcting the outlet temperature of the chiller,the optimal control quantity of the controller was obtained through local and dynamic optimization.The simulation results showed that the dynamic matrix control algorithm could achieve stable and non-overshoot control,and the adjustment speed of the effluent temperature was more than three times higher than traditional PID control.The anti-interference ability was also better than traditional PID algorithm.
