    Abstract:

    A temperature control method is designed for centrifugal-temperature composite chamber for calibration of accelerometers. A design scheme is proposed for the temperature control system at first. And then, aiming at gas temperature large inertia and large delay characteristics, a Predictive PI-PID cascade control method is proposed that Predictive PI control and cascade control method are combined for the temperature control of the centrifugal-temperature composite chamber. It overcomes the poor robustness of simple PID and the adverse effects of pure delay system. The results show that: predictive PI-PID cascade control system is robust and has good regulation performance, and the performance is better than the PID and traditional PID-PI Cascade Control System.
