Abstract: Systems and methods for automatic feedback control are provided. According to one embodiment of the disclosure, a method for automatic feedback control may commence with receiving high-level control references by a low-level controller communicatively coupled to a high-level controller via the network connection. The method may further include generating, by the low-level controller, low-level control references for a hardware asset based at least in part on the high-level control references. The method may continue with transferring control of the hardware asset to the low-level controller in response to a loss of the network connection. The method may further include adjusting the low-level control references by a low-level control mechanism associated with the low-level controller in response to the loss of the network connection.

Abstract: Exemplary embodiments pertain to a system that can include a high-level controller coupled to a low-level controller for controlling a physical asset. In one exemplary implementation, the high-level controller executes a first finite state machine for controlling a power generation unit via a network. The low-level controller executes a second finite state machine that may have fewer states than the first finite state machine. The second finite state machine places the low-level controller in a default mode of operation for controlling the power generation unit under various conditions such as when the high-level controller is controlling the physical asset during a normal mode of operation; when the high-level controller is revising the first finite state machine; when the high-level controller is controlling the physical asset using a revised first finite state machine; and/or upon detecting a loss of communications between the high-level controller and the low-level controller.
