ANTIWINDUP AND OVERRIDE CONTROL FOR EXPONENTIALLY UNSTABLE SYSTEMS WITH ACTUATOR CONSTRAINTS

Control of exponentially unstable plants with an actuator having both position and rate saturations is investigated. The standard antiwindup technique is not able to increase the very limited radius of attraction. A novel design technique based on the override technique is proposed which enlarges th...

Summary:Control of exponentially unstable plants with an actuator having both position and rate saturations is investigated. The standard antiwindup technique is not able to increase the very limited radius of attraction. A novel design technique based on the override technique is proposed which enlarges the radius of attraction, such that the actuator working range can be utilized.
