This paper proposes a new speed control method for hydraulic elevators to save on operating energy and improve the smoothness of changes in car speed. The car is operated by varying the speed of a hydraulic pump driven by a speed controlled induction motor. The leakage flow of the pump depends on the number of passengers and oil temperature, and induces a difference between command and actual car speed. To improve the performance of speed control and suppress the vibration of the car, a noncolocated feedback control method is employed. The dynamics of a hydraulic elevator are investigated to design a controller of sufficient robustness. The controller designed is verified by numerical simulations and the results indicate the good performance of the developed hydraulic elevator system.
