Abstract

An adaptive feedforward mechanism is combined with active disturbance rejection control (ADRC) to provide fast tracking performance without requiring high observer bandwidth. The feedforward controller uses an inverse plant model that is continuously adjusted as the plant changes. Providing this controller with reasonable initial conditions dramatically improves how quickly it can derive a reasonable inverse model. Simulation results demonstrate tracking and disturbance rejection capabilities at a low cost, i.e. bandwidth.
