The objective of this study is to improve the servo stiffness and stability of the high-accuracy car level compensation device in a hydraulic elevator, which is used to reduce the car position fluctuation caused by passengers getting on or Off. The previous compensation device is composed of an electro hydraulic position servo system. In order to enhance this system, an observer is introduced to estimate the car acceleration, and a pseudo-acceleration feedback control is applied. The performance of the modified compensation device is examined by carrying our stability analysis and an experiment, and it is shown that the proposed control method halves the position fluctuation and quarters the settling time compared to the previous method.
