Abstract:
In one embodiment, a control system supports an unlimited number of feedback control loops all sharing control of a component. A component performance rate or “speed” is used as a common metric for negotiating control of the component. Each control loop continuously monitors a system parameter it is tasked with regulating, compares it to a setpoint for that system parameter, and “requests” a speed in relation to the deviation of the associated system parameter from the corresponding setpoint. A controller receives the requested speeds as dynamic inputs and selects one of the requested speeds according to predefined selection logic. The controller communicates the selected speed to an actuator, which causes the component to operate at the selected speed. In this manner, the control system in effect negotiates control of the component in a way that ensures that all of the system parameters are being managed within safe limits.
