Adaptive Control of Above Knee Electro-Hydraulic Prosthesis
Journal of Biomechanical Engineering, 1992Conventional designs of an above-knee prosthesis are based on mechanisms with mechanical properties (such as friction, spring and damping coefficients) that remain constant during changing cadence. These designs are unable to replace natural legs due to the lack of active knee joint control. Since the nonlinear and time-varying dynamic coupling between

Intelligent-PI controller for electro-hydraulic system
2016 4th International Conference on Control Engineering & Information Technology (CEIT), 2016Electro-hydraulic actuators have been widely applied in industry with position or pressure control. Nevertheless, the conventional linear control technology is not able to satisfy the requirement of improving the control precision due to the nonlinearities of hydraulic systems. This paper presents two control strategies based on intelligent-PI in order
