Abstract :
In automatic control applications, the relay nonlinearity is used to describe a sensor or actuator behavior. Such nonlinearity combined with stabilizing feedback loops often leads to limit cycles for the closed loop system. We study the control of such limit cycles by use of a proportional+integral control law with the delayed output of a relay sensor
