Trajectory Tracking Control Using a Hydraulic Transformer
Throttling loss of a hydraulic system is a major contributor to the low system efficiency. Hydraulic transformers can potentially be used as an energy efficient, throttle-less control approach for multi-actuators systems powered by a common pressure rail (CPR). The transformer transforms the input CPR pressure to the desired pressure of the actuator instead of throttling it. Regenerative energy...
متن کاملRobust Control of a Hydraulic Cylinder using Observer-based Nonlinear Controllers: Theoretical Development and Experimental Validation
Hydraulic cylinders are actuators with strongly nonlinear behavior. They are widely used in several industrial areas, such as heavy machines, cranes, robots, and so on. The dynamical behavior of hydraulic differential cylinders can be described by a coupled set of nonlinear differential equations. Motion control of power trains, drive trains, or even actuators has been in the focus of several s...
متن کاملRobust position control of electro-hydraulic actuator systems using the adaptive back-stepping control scheme
In general, the position control of electro-hydraulic actuator (EHA) systems is difficult because of system uncertainties such as Coulomb friction, viscous friction, and pump leakage coefficient. Even if the exact values of the friction and pump leakage coefficient may be obtained through experiment, the identification procedure is very complicated and requires much effort. In addition, the ide...
متن کاملPassive Control of a Hydraulic Human Power Amplifier Using a Hydraulic Transformer
The hydraulic human power amplifier is a tool that uses hydraulic actuation to amplify the force that the human exerts on it. Our control objective and framework are to make the system behave like a passive mechanical tool when interacting with the human and with the work environment with a specified power scaling factor. A virtual velocity coordination control approach casts the human power am...
متن کاملThe Position Control of the Hydraulic Cylinder Controlled by the High-Speed On-Off Valve
This paper aims to research the position control of the hydraulic cylinder controlled by the highspeed on-off valve to realize the precise position control. A compound algorithm of proportional integral & speed feedforwarddisplacement feedback is put forward based on the research on the relationship between the duty ratio and the past flow for the high speed on-off valve. The speed feedforwardd...
