<P>PROBLEM TO BE SOLVED: To provide a control device for an elevator permitting the car speed to smoothly follow a desired car speed command and reducing uncomfortable car vibration. <P>SOLUTION: This control device controls a motor 11 driving a car via rope using a signal of a speed detector 2 of the motor as a feedback signal, and comprises a speed torque command means 40 including a command loop compensator 34 comparing a speed command of the car and a speed command to the motor to output a torque command to the motor, and a motor model 20 inputting the torque command and outputting the speed command to the motor; and a speed control means 41 including a speed loop compensator 35 outputting a speed compensating signal from a deviation between a motor speed signal and the speed command to the motor, compensating the torque command by the speed compensating signal to drive the motor. The motor model 20 is constituted by the product of a rigid body property model deeming a mechanical system including the car, a balance weight and a rope as a perfect rigid body and a flexible property model including a spring constant and a damping coefficient of the rope. <P>COPYRIGHT: (C)2004,JPO |
