| Abstract: | Based on the tension control requirement in high-speed unwinding process which took magnetic powder brake as actuator,a two-quadrant pulse-width modulation(PWM) constant current chopper technique based on high pulse to improve rapid respond performance of the magnetic powder brake was presented,a simple tension self-stabilization control algorithm fits wide range variation was introduced,and the technical implementation scheme of the tension controller was proposed.Theory analysis and application indicate the scheme has good control performance,easily used and convenient operated. |
