Designing robust force control of hydraulic actuators despite system and environmental uncertainties.

Designing robust force control of hydraulic actuators despite system and environmental uncertainties.

The article presents the design of a robust force controller for a hydraulic actuator interacting with an uncertain environment via quantitative feedback theory (QFT). After the derivation of a realistic nonlinear differential equation model, a linearized plant transfer function is developed. The ef...
