“…For the fuel quantity actuator system, there exist nonlinear and multi-source disturbances. A continuous sliding-mode control based on a multi-source disturbance observer is proposed, which can effectively depress the steady-state fluctuation [16]. A SMC volume control scheme for a servo pump-hydraulic cylinder system is discussed, which constitutes a pump-controlled servo motor for a steam control valve [17].…”

A piston piezoelectric (PZT) pump has many advantages for the use of light actuators. How to deal with the contradiction between the intermittent oil supplying and position control precision is essential when designing the controller. In order to accurately control the output of the actuator, a backstepping sliding-mode control method based on the Lyapunov function is introduced, and the controller is designed on the basis of establishing the mathematical model of the system. The simulation results show that, compared with fuzzy PID and ordinary sliding-mode control, backstepping sliding-mode control has a stronger anti-jamming ability and tracking performance, and improves the control accuracy and stability of the piezoelectric pump-controlled actuator system.
