Control system with optimized periodic adjustments of system control settings using MARS-based MILP optimization

A control system for controlling a physical system, wherein the physical system comprises:

• adjustable operational control settings, and
• a plurality of physical characteristics each associated with a predictor variable,
• wherein at least one of the predictor variables is a directly-controllable variable associated with one of the operational control settings and directly controls one of the plurality of physical characteristics that is associated with the respective directly-controllable variable,
• wherein at least one of the predictor variables is a controllable variable associated with any of the plurality of physical characteristics that is affected by any of the plurality of physical characteristics associated with any directly-controllable variable,
• the control system comprising:
• a multivariate adaptive regression splines (MARS) modeler;
• a mixed integer linear programming (MILP) transformer;
• and
• an optimization engine,
• wherein, during a predefined time horizon that includes multiple time intervals each followed by a control point:
• (a) the MARS modeler is configured to (i) construct a MARS prediction model using those of the predictor variables associated with the time interval that immediately precedes the respective control point, and (ii) use the MARS prediction model to define an optimization problem for the respective control point,
• (b) the MILP transformer is configured to transform the optimization problem into a mixed integer linear programming problem,
• (c) the optimization engine is configured to solve the MILP problem, to determine at least one optimized value for any given one of the directly-controllable variables, and
• (d) the control system is configured to adjust, using the at least one optimized value, the adjustable operational control setting corresponding to the given directly-controllable variable, to thereby control the physical characteristic associated with the directly-controllable variable during the time interval immediately following the respective control point.
