- 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.
