Closed-Circuit Hydraulic Actuator

This example shows a closed-circuit hydraulic actuator driven by a variable-speed motor. The actuator is arranged as a closed system with two replenishment valves (check valves) and a spring accumulator serving as a replenishment reservoir. The motor velocity is controlled by the difference between the commanded and actual actuator position. The actuator acts against a spring, damper, and a time-varying load.
