The Positional Control System with Inverter - 2 Phase Servomotor Controlled by Microprocessor

This paper describes a new approach to the control problem based on the use of inverter- 2 phase servomotor drives in which complementary pairs of power MOSFET s are used to implemem the inverters interfaced to the Z- 80 microprocessor. An attempt have been made to eleminate harmonics by using PWM techniguse and to reduce control system by phase control method. The position control of the 2 phase servomotor operated by PWM system and phase control method is applied. As controller, the PI algorithm is adapted. The transient respones of the motor position are simulated by digital computer and verified by laboratory experiment.
