Beschreibung
Zusammenfassung:	A hydraulic actuator control system that includes an actuator. A pump pumps a hydraulic fluid to move the actuator. A first control valve fluidly couples to the pump. The first control valve provides a first hydraulic fluid flow to the actuator. A maximum first hydraulic fluid flow through the first control valve is less than a maximum required hydraulic fluid flow of the actuator. A second control valve fluidly couples to the pump. The second control valve provides a second hydraulic fluid flow to the actuator. A maximum second hydraulic fluid flow through the second control valve is less than the maximum required hydraulic fluid flow of the actuator. A controller controls the first control valve and the second control valve to provide the hydraulic fluid to the actuator.
