Adaptive control for systems with two binary measurements

Abstract

We propose a new type of binary controller for control loops with two binary measurements and an analog, continuous actuator. Unlike common binary controllers, the proposed adaptive controller requires no continued oscillation of the plant output. Instead, the proposed controller adapts an internal plant model to compute an optimal plant input so that the plant output settles on a constant value in between the two binary sensors. The parameter identification is fully automated and requires no user interaction, so that the proposed controller is as simple to implement as a conventional on-off controller. We evaluate the controller in a laboratory test setup and compare the energy comsumption to established control approaches.
