Abstract:
A motor control system for a hoist drive having an electric motor operationally connected to a hoisting member for hoisting a load, the motor control system being adapted to generate a final angular frequency reference (ω*s) for control of the electric motor, the motor control system comprising a power limiter means adapted to generate a correction term (ωs,cor) for angular frequency reference. The power limiter means comprises an integrating controller means, the power limiter means being adapted to generate the correction term (ωs,cor) for angular frequency reference using output signal IP of the integrating controller means, initial data of the integrating controller means including information relating to actual value of the power of the electric motor and a power related limit value of the electric motor.
