Abstract

Using the describing function method, engineers in the 1950?s and 1960?s conceived of novel nonlinear compensators in an attempt to overcome the performance limitations inherent in linear time-invariant (LTI) control systems. This paper is concerned with a subset of such devices called "reset controllers" which are LTI systems equipped with mechanism and law to reset its states to zero. This paper reports on a design procedure and a laboratory experiment in which the resulting reset controller provides better tradeoffs than LTI compensation. Specifically, we show that reset control almost doubles the level of sensor-noise suppression without sacrificing either disturbance-rejection performance or gain/phase margins. To the best of our knowledge, this is the first experimental demonstration of reset control in the literature.
