Abstract: Systems and methods for health monitoring and upgrade of a distributed controller are provided. According to one embodiment of the disclosure, a method for health monitoring and upgrade of a distributed controller may commence with receiving, by a lower level controller from a high-level controller, high-level control references. The method may further include generating low-level control references for a hardware asset based at least in part on the high-level control references. The method may include monitoring the network connection and detecting an error in the network connection. In response to the detection of the error in the network connection, a control of the hardware asset may be transferred to the low-level controller. The method may further include determining that the network connection has been restored. In response to the determination that the network connection has been restored, the control of the hardware asset may be transferred to the high-level controller.

Abstract: A method includes determining a commanded load rate of change of an industrial system, wherein the commanded load rate of change comprises a rate of load placed on an industrial machine of the industrial system. The method also includes determining a measured load rate of change of the industrial system based at least in part on an output power of the industrial system. The method further includes determining a variable multiplier based at least in part on the commanded load rate of change and the measured load rate of change. The method also includes applying the variable multiplier to a load rate command to the industrial system to generate a multiplied load rate command. The method further includes sending a signal to the industrial system to control the rate of the load placed on the industrial machine based at least in part on the multiplied load rate command.

Abstract: A system is provided. The system includes a gas turbine, the gas turbine having an operating space during operation and a current operating point during operation, a computing device communicatively coupled to the gas turbine and configured to calculate, based on the current operating point of the gas turbine, the operating space for the gas turbine by solving for a plurality of corner points that define the operating space, and display, to a user, a graph that includes the calculated operating space and the current operating point.

Abstract: A system may include a controller that may control operations of a device according to a control loop and characterize a frequency response of the device while the device is operating. The controller may characterize the frequency response by adding a perturbation signal to any signal in the control loop. The controller may then determine a first transformed signal by performing a first discrete Fourier transform on a first signal in the control loop at a frequency of the perturbation signal and determine a second transformed signal by performing a second discrete Fourier transform on a second signal in the control loop at the frequency of the perturbation signal. The controller may then determine the frequency response at the frequency by comparing a first amplitude and a first phase of the first transformed signal to a second amplitude and a second phase of the second transformed signal.
