Abstract

This paper focuses on the stabilization of an internal model based control system for reference tracking/disturbance rejection, where the physical plant is linear time invariant while the generating dynamics of the reference/ disturbance is time varying. Given the inevitable linear time varying (LTV) nature of the internal model unit resulting from the time varying generating dynamics, a critical problem to be addressed is the design of a low order and robust stabilizer for the entire augmented system. While a parameter-dependent output injection based stabilizer was introduced in our previous work, the new method proposed in this paper reduces the conservativeness in the control synthesis and thus enables a more effective control design especially for the problem involving LTI physical plant with LTV internal model dynamics. The proposed approach is then validated through experimental investigations on a camless engine valve actuation system, where robust and precise tracking performance is demonstrated.
