Programmable deadband current regulator |
摘要 |
A method for supplying the excitation to a four quadrant drive DC electric motor having a forward and reverse controllable bridge rectifier power regulators for controlling the direction of motor rotation. The motor control system is capable of operating in a continuous and discontinuous current mode of operation and includes an electronic control circuit for calculating a firing angle from desired and measured system parameters. The electronic control system includes a reversing controller for developing a current command for generating firing pulses to fire selected switching elements in the power regulators for controlling the magnitude and polarity of the excitation, and a current sensor for sensing motor current. The method provides a smooth, continuous transitioning between the forward and reverse bridge in response to a sensed requirement for reversing excitation to the motor.
