Force Control of Hydraulic Actuators using Additional Hydraulic Compliance

Strojniški vestnik - Journal of Mechanical Engineering, 2018
This paper presents an approach for improving the performance of hydraulic force control systems by adding hydraulic compliance. Typically, force control systems require a flexible coupling system, such as a spring between the actuator and the load, to achieve a non-oscillatory response.
