Abstract:
Technical solutions described herein include a method of controlling, in an electric power steering system, a steering angle according to a target steering angle by computing an initial value of an integral control term in a proportional integral derivative (PID) control loop used to calculate a control output signal, such as a motor torque command. The initial value of the integral control term is computed as a negative of the initial value of the feedforward term minus the initial value of the feedback term. The initial value of the integral control term corresponds to an initial value of a control output. Accordingly, the technical solutions described herein facilitate handling non-zero initial condition in Electric Power Steering angle control.
