Hydraulic servo system plays an important role in industrial fields due to the advantages of high response, small size-to-power ratio and large driving force. However, inherent nonlinear behaviors modeling uncertainties are main obstacles for hydraulic achieve tracking performance. To deal with these difficulties, this paper presents a backstepping sliding mode controller improve dynamic perfor...

Abstract: This paper is to develop an optimal electro-hydraulic dual-shaking table system with high waveform replication precision. The parameters of hydraulic cylinders, servo valves, hydraulic supply power and gravity balance system are designed and optimized in detail. To improve synchronization and tracking control precision, a hybrid control strategy is proposed. The cross-coupled control ...

Abstract This study presents a method of computer support for the design hydraulic servo dedicated to aircraft control system. A 3D geometric model was developed, which enabled simulation its kinematics. The paper that enables dynamics mechanisms. servomechanism takes into account movement distributor slider and actuator piston rod under influence forces occurring in servo. As result simulation...

the ball and beam system is one of the most popular laboratory setups for control education. in this paper, we design a fuzzy pd cascade controller for a ball and beam system using asexual reproduction optimization (aro) technique. the ball & beam system consists of a servo motor, a grooved beam, and a rolling ball. this system utilizes a servo motor to control ball’s position on the beam. chan...
