Abstract :
The intermittent type reaction still inertia is big, lags is in a big way, time-variable is slow, when switching between refrigeration and heating, the misalignment is serious, the traditional PID control to be very difficult to satisfy the performance requirement. Therefore this article is based on the recursion least squares method and the generalized predictive control principle, has designed a set of simple practical control system, on the Kingview platform of Beijing Wellincontrol, uses the traditional PID control in the heating-up period; during 60-70°C the refrigeration heating switching step, uses the generalized predictive control, solves the vibration which the serious misalignment brings. The experimental result indicated that compares with the traditional PID control plan, this one strengthened system´s robustness and the compatibility, the system vibration reduced largely.
