Calculation techniques for parameters of a digital PI controller in an electrical drive


Various methods of calculating parameters of a digital PI controller for a microcontroller system are considered. The adequacy of replacement of a PWM VSI, system of current measurement, and a digital controller by an equivalent inertial element for the calculation of miocrocontroller parameters is shown. The possibility of setting time reduction to one PWM period weithout overshoot and ringing with PI controller is shown.
