Research on Microcomputer Control System of D.C.Motor Sliding-Mode Variable Structure

Based on the study of variable structure system theory, a speedand position D.C.PWM digital serve system controlled by mic-roprocessor is designed and reallzed.Sliding variable structurecalculation method is used in this system,and new-style powerVMOS transisters are adopted in the power amplifier.Computersimulation and experimental results demonstrate that this systemis more stable,speedy and insensitive to parametric variationsand load disturbances than traditional PI regulator system.
