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.

A Complete Analysis and a Novel Solution for Instability in Pump Controlled Asymmetric Actuators
Journal of Dynamic Systems, Measurement, and Control, 2015This 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.

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.

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.

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.
