Latest Patents

Yi-Chieh Chen holds a patent for a "System and method for static auto-tuning electric motor." This invention presents a static auto-tuning system and method for controlling the operation of a motor within a system. The system generates a speed reference signal that results in a speed response of the motor. Closed-loop feedback magnifies the rotating friction effect to an observable level. The inertia and rotating friction coefficient values of the system are estimated based on the speed frequency response and a virtual damping coefficient. A fixed low-frequency speed signal may yield a first frequency response function for determining virtual damping, while a variable frequency excitation signal may produce a second frequency response function for determining the inertia and rotating friction characteristics. Closed-loop gains are established based on these characteristics, and the excitation signal can be sampled to identify and store peak values, producing an envelope of peak values for determining the gain response. Ultimately, the operation of the motor is controlled using the determined gains.
