A Complete Analysis and a Novel Solution for Instability in Pump Controlled Asymmetric Actuators

Journal of Dynamic Systems, Measurement, and Control, 2015
This paper addresses the stability problem of pump controlled asymmetric hydraulic actuators and proposes a physical solution for it. The system under consideration utilizes a shuttle valve to compensate for unequal flow rates due to the asymmetry in the actuator.

Nonlinear control of direct-drive pump-controlled clutch actuator in consideration of pump efficiency map

Control Engineering Practice, 2019
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.

Modeling and Adaptive Robust Force Control of a Pump-Controlled Electro-Hydraulic Actuator for an Active Suspension System

2019 IEEE Conference on Control Technology and Applications (CCTA), 2019
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.

LuGre model–based robust adaptive control for a pump-controlled hydraulic actuator experiencing friction

Transactions of the Institute of Measurement and Control
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.

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.
