Claim Text:
1. A control system, comprising: a controller that, in operation, controls operation an industrial process; the controller being configured to, in operation, perform the following steps: determining, using a control system, a first feasible control trajectory comprising a first control action to implement in the process during a first future time step and a second control action to implement in the industrial process during a second future time step after the first future time step; determining, using the control system, a second feasible control trajectory comprising the second control action by time shifting the first feasible control trajectory from the first future time step to the second future time step; determining, using the control system, a third feasible control trajectory comprising a third control action to implement in the industrial process during the second future time stamp by performing a first optimization search based at least in part on state of the industrial process and constraints on operation of the industrial process; determining, using the control system, a first cost associated with implementing the second control action during the second future time step based at least in part on an objective function; determining, using the control system, a second cost associated with implementing the third control action during the second future time step based at least in part on the objective function; and controlling, using the control system, the operation of the industrial process by instructing the industrial process to implement the second control action or the third control action based at least in part on the first cost and the second cost.
