Observer design for estimating motor velocity of brush electric power steering system
Observer design for estimating motor velocity of brush electric power steering system
A motor control system of a motor is provided. The system includes a state estimation observer that computes an estimated velocity based on an inertia-damping response to the dynamics of the motor shaft, a torque command signal, and the compensated command signal. This compensated signal comes from a proportional-integral-derivative (PID) controller that determines a difference between a sensed position and an estimated position. The estimated position is determined by the estimated velocity and an integrator. The control system may also include a motor-velocity based lowpass filter which applies a filter to the estimated velocity.
