Disclosed are a fluid control system and method of controlling operating pressures within a fluid system, where the fluid control system includes a choke assembly, a pressure generating device, and a linear motor. The choke assembly may include a housing and a choke member adapted for movement in the housing, controlling the flow of a fluid from an inlet passage to an outlet passage. The fluid applies a force on a first end of the choke member. The pressure generating device may be fluidly connected to a chamber and may contain a control fluid that applies a first force on a second end of the choke member. The linear motor may apply a second force on the second end of the choke member. The difference between the forces applied to the first and second ends of the choke member may affect the movement of the choke member in the housing.
