| Abstract: | The design was based on liquid - viscosity speed governor. The designer combined it with program - controller, and utilized high - unit to realize digitization speed given instead of traditional machine given. On basis of speed chart, the designer used PID units to achieve double closed- loop control by making up speed and current regulator. And realized automatic control for mining AC elevator. The flow diagram and the program were designed. |
