Information transfer in stochastic optimal control theory with information theoretic criterial and application

A computer-implemented method for transmitting information signals in a control system, the method comprising:

• receiving, at a controller of a control system, an information signal to be propagated through the control system, where the information signal includes data to be transmitted through the control system;
• determining, at the controller of the control system, a control signal to control one or more operations in the control system;
• encoding, at the controller of the control system, the received information signal to produce an encoded information signal, wherein encoding the received information signal comprises:
• determining a control-coding capacity of the control system based on a system model of the control system, wherein the control-coding capacity is a maximum rate of transmitting information signals through the control system, wherein determining the control-coding capacity includes solving an optimization of a representation of the control-coding capacity based on the system model, wherein the representation of the control-coding capacity includes a plurality of conditional control input distributions, and
• implementing a coding scheme to encode the received information signals based on the determined control-coding capacity;
• transmitting, by the controller, an encoded message using the control system as a communication channel, where the encoded message comprises the control signal and the encoded information signal.
