| Abstract: | A PWM speed-control system of variable frequency controlled by a chip microprocessor 8031 is introduced in this paper.This paper presents the calculating formula of the thyristor's turn-on time and the measure of deducing harmonics. The major block diagrams of control programs, and the experimental result are also presented. |
