Bang/Bang Control with a Hysteresis Deadband

Video Description

In this video we improve on the bang/bang control algorithm by adding a hysteresis deadband. This makes the system more robust to actuator/control chatter at the cost of slightly increased over/undershoot. We investigate how to implement this controller in Simulink using Stateflow to build finite state machines. We also demonstrate how Stateflow is compatible with the Simulink Support Package for Arduino Hardware which allows us to execute Stateflow charts on an Arduino in real-time.
