Method and Apparatus for Robust Emulation of Mechanical Load by using Disturbance Observer

摘要

The present invention provides a method for emulating a motor under test connected to a dynamometer having a specific load, the method comprising: receiving an electric torque value acting on the motor under test; Receiving a load torque value of a specific dynamic to be emulated; Detecting the rotational speed of the motor under test; And a dynamometer torque acting on the dynamometer using a first value that is the product of the rotation speed multiplied by the friction of the dynamometer, a second value that is the product of the rotation speed multiplied by the inertia of the dynamometer, the load torque value, and the electric torque value. Generating an instruction; And driving the dynamometer according to the dynamometer torque command.
