Continuous position control by symbolic input and output

This paper concerns a control problem for a specification which requires a finer description than the resolution of available sensors and actuators. Such a situation may arise when a given control specification is to be achieved as accurate as possible while sensors are kind of limit switches and actuators are on/off control architecture. In this paper, a ball position control system is taken. The experimental setup is modelled with rolling friction. For the experimental setup, we propose a control algorithm based on discrete input and output and continuous state estimation. Finally, the proposed method is applied to the experimental setup to demonstrate its effectiveness as well as numerical simulation
