Sigmoid function aided Zhang dynamics control for output tracking of time varying linear system with bounded input
This paper investigates the output tracking control of time varying linear (TVL) system. Note that the input is always limited in a range due to actuator physical constraints or energy saving purposes. By combining the Zhang dynamics (ZD) and the sigmoid function, an effective controller, termed sigmoid function aided ZD (SFAZD) controller, is designed for tracking the TVL system. Simulative verifications substantiate that the proposed SFAZD controller can achieve accurate tracking results, and limit the input in the range during the tracking process.
