Abstract
A control device may include at least a first electromechanical setpoint controller having a prime mover that applies a setpoint force in response to at least a controller signal, and a controller circuit that generates at least the controller signal in response to setpoint control data. A pneumatic controller may have at least one gas flow inlet and a flow regulator that varies a gas flow property in response to the setpoint force.
