Self-commissioning controller for a field-oriented elevator motor/drive system

摘要

A self-commissioning controller 7 for a field-oriented elevator motor controller 14 includes calculating an integral gain KI, a proportional gain Kp, and an overall gain (Gc) for the motor controller; obtaining initial values of a rotor time constant τR, magnetizing current Id, and motor torque constant KT for the motor controller 14, and obtaining a value of a motor transient inductance Lσ; calculating final values for said rotor time constant τR and magnetizing current Id, using said transient inductance Lσ; and calculating a system inertia J* parameter for speed loop compensation 16 within the motor controller 14. The controller 7 may also include calculating the initial values for τR, Id, and KT*, and performing self-commissioning automatically upon receiving a command from a service tool 80.
