Abstract

A new generation of crane controllers with higher reliability and controllability is designed compared with present home and abroad crane controllers. Its power unit is isolated from the control unit with optical fibers. It has two layers of power isolation. The voltage value of input signals is raised. The interference resisting capability is raised by replacing transistor circuits with PWM firing technology. There are six control points to control brakes. Besides, the control system reliability and performance are enhanced by superseding mere PID control with combination of PID control and stator current close loop. Tests proved the effectiveness.
