Control system for a drive having an asynchronous motor
In the case of a control system (140) for a drive having an asynchronous motor, in particular for a railroad vehicle, which control system (140) comprises a first control loop (141) for motor control, and a second control loop (142) which is connected to the first control loop (141) and has an adhes...

| description | In the case of a control system (140) for a drive having an asynchronous motor, in particular for a railroad vehicle, which control system (140) comprises a first control loop (141) for motor control, and a second control loop (142) which is connected to the first control loop (141) and has an adhesion controller (125), an improved control response is obtained in that the motor control system is designed as a stator frequency control system (127), and in that an actual torque value (Mact) for the asynchronous motor is derived within the motor control system, and in that the two control loops (141, 142) are connected to one another in such a manner that the actual torque value (Mact) from the motor control system is used as the actual value for the adhesion controller (125), and in that the adhesion controller (125) presets a nominal stator frequency value (fs,nom) for the motor control system. |
