Autotuning method and system based on the bilinear-quadratic filter

摘要

A built-in autotuning system of a motor control system provides an autotuning of the motor control system based on BQF. The system measures the effective inertia and determines whether there exists a high-frequency resonance. If there is a high-frequency resonance, the system sets the BQF as a low pass filter, otherwise the system sets the BQF as a high pass filter. The system then adjusts the gains of the controller to set the phase and gain margins within a specified values.
