Backstepping Sliding-Mode Control of Piezoelectric Single-Piston Pump-Controlled Actuator [PDF]

Actuators, 2021
A piston piezoelectric (PZT) pump has many advantages for the use of light actuators. How to deal with the contradiction between the intermittent oil supplying and position control precision is essential when designing the controller.

Energy management in pump-controlled actuators

Frontiers in Mechanical Engineering
Pump-controlled actuators, or more generically, hydrostatic actuators, have the significant advantage of not relying on valves to control the cylinders. This results in much better energy usage compared to traditional valve-controlled systems.

A Singular Perturbation Theory-Based Composite Control Design for a Pump-Controlled Hydraulic Actuator with Position Tracking Error Constraint

Actuators, 2023
Pump-controlled hydraulic actuators (PHAs) contain slow mechanical and fast hydraulic dynamics, and thus singular perturbation theory can be adopted in the control strategies of PHAs.

Pump-Controlled Actuators with Dump Valves

Linköping Electronic Conference Proceedings, 2021
The electrification trend means an increased focus on the energy efficiency of mobile hydraulic systems. In turn, this means an increased focus on so-called pump-controlled systems, where actuators are controlled by pump flow rather than valve throttling.
