The vehicle will generate an amount of current while the electric just starting to regeneratively brake. In order avoid impact high on traction battery, a novel electrohydraulic hybrid has been proposed. main power source is supplied by drive system, and hydraulic system performs auxiliary that fully exerts advantages system. A proper regenerative braking control strategy presented, parameters ...

According to the nonlinear and time-varying uncertainty characteristics of direct drive electrohydraulic servo control system, a self-tuning fuzzy PID control method with speed change integral and differential ahead optimizing operator is put forward by combining fuzzy inference and traditional PID control in this paper. The rule of fuzzy logic is designed, the membership function of the fuzzy ...

Electro hydraulic drives are often used where the dynamic response requirements of the driven load in terms of speed, cycling, accuracy and stability are particularly severe. One such application is the control and drive system associated with a high frequency hydraulic vibrator. A hydraulic shaker controls a valve which directs high pressure hydraulic fluid to generate controlled vibration. Hy...

A passive control scheme for the bilateral teleoperation of an electrohydraulic actuator and a motorized joystick is proposed. The overall system enables a human operating a motorized joystick to feel as if he is manipulating a rigid mechanical tool with which the work environment is also in contact. By ensuring that the closed loop system behaves like a passive two port device, safety and stab...

Biodegradable materials decompose and return to nature. This functionality can be applied derive robotic systems that are environmentally friendly. study presents a fully biodegradable soft actuator, which is one of the key elements in “green” robotics. The working actuator based on an electrohydraulic principle, similar hydraulically amplified self-healing electrostatic actuators. developed th...
