Abstract: This essay exp licates the block diagram of AC machine timing system with 89C51 singlechip as its core control component, analyzes severalmajor control circuits, and brings forward program flow chart of the control system. This system modifies the p revious comp lexity in designing analog circuit, enhances the controllability of the speed ofAC machine, and increases the precision of the timing system.
Key words: singlechip; control circuit; timing system
