Abstract
Methods and apparatus for automatic tuning of parameters for field-oriented control (FOC) of a BLDC motor with a controller with user input. Automatic tuning can include measuring electrical parameters comprising Phase resistance (Rs), Phase inductance (Ls), and Back-electromotive force (BEMF) constant (Ke). Automatic tuning can further include tuning of ac alignment and start-up processing, tuning of a current closed loop, and tuning of a speed closed loop.
Claims35
A method of automatically tuning a controller for a field-oriented control (FOC) electric motor, comprising:
- receiving user input for parameters for tuning the controller;
- measuring phase resistance and phase inductance of the motor;
- and
- automatically tuning the controller for at least one type of tuning based on the user input and the measured phase resistance and phase inductance of the motor.
A system to automatically tune a controller for a field-oriented control (FOC) electric motor, comprising:
- memory and at least one processor configured to:
- receive user input for parameters for tuning the controller;
- measure phase resistance and phase inductance of the motor;
- and
- automatically tune the controller for at least one type of tuning based on the user input and the measured phase resistance and phase inductance of the motor.
