This paper employs the quantitative feedback theory (QFT) to design a robust fixed-gain linear velocity controller for a newly developed single-rod pump-controlled actuator. The actuator operates in four quadrants, with a load force becoming resistive or assistive alternatively.

This paper presents an adaptive robust force control of a pump-controlled electro-hydraulic actuator for application in an active suspension system. To overcome the limitations of a linearized model for a pump-controlled electro-hydraulic actuator (EHA), which has been already studied in existing literature, an improved nonlinear model is proposed.

Abstract Pump-controlled hydraulic system, compared with the valve-controlled one, has simplified structure and increased efficiency, but the dynamic response is poor. This paper presents a high precision, fast dynamic response, and computational low-cost controller for a novel direct-drive pump-controlled hydraulic system.

In this paper, a LuGre model–based robust adaptive control (RAC) approach is presented for a pump-controlled hydraulic actuator. We first decompose the LuGre friction model into its steady-state model and a lumped dynamic part applying the mean value theorem, which are compensated by a feedforward term and a robust adaptive term, respectively.

High-precision control technology for the pump controlled single-rod actuator (PCSA) system is in high demand in industrial applications. In the PCSA system, there are both matched and mismatched uncertainties. However, it is still a challenging task for existing observer-based controllers to simultaneously observe and compensate for the uncertainty of

Development of a pump-controlled double rod electro-hydrostatic actuator
This thesis addresses the modeling, state estimation, and robust control of Electro- Hydrostatic Actuators (EHA) for high-precision applications. A detailed mathematical model of the EHA system, encompassing hydro-mechanical, electrical, and control subsystems, is developed.openaire +1 more source
