Sequential deterministic optimization based control system and method

A control system configured to control operation of one or more actuators to facilitate performance of an industrial automation process, wherein the control system comprises:

• memory configured to store executable code;
• and
• processing circuitry communicatively coupled to the memory, wherein the processing circuitry is configured to execute the executable code to:
• perform an infeasible search initiated from a first point outside a feasible region during a first portion of a predetermined sample period based at least in part on one or more sensor samples indicative of a state of the industrial automation process to determine a first control trajectory of a plurality of input variables of the industrial automation process;
• perform a feasible search initiated from a second point inside the feasible region during a second portion of the predetermined sample period based at least in part on the one or more sensor samples indicative of the state of the industrial automation process to determine a second control trajectory of the plurality of input variables of the industrial automation process when the first control trajectory is not feasible;
• and
• control performance of the industrial automation process at least in part by:
• instructing the one or more actuators to perform a first control action determined based on the first control trajectory when the first control trajectory is feasible;
• and
• instructing the one or more actuators to perform a second control action determined based on the second control trajectory when the first control trajectory is not feasible.

A tangible, non-transitory, machine-readable medium storing instructions executable by processing circuitry of a control system, wherein the instructions comprise instructions to:

• perform, using the processing circuitry, an infeasible search initiated from a first point outside a feasible region during a first portion of a predetermined sample period based at least in part on one or more sensor samples indicative of a state of an industrial automation process being controlled by the control system to determine a first control trajectory of a plurality of input variables of the industrial automation process;
• perform, using the processing circuitry, a feasible search initiated from a second point inside the feasible region during a second portion of the predetermined sample period based at least in part on the one or more sensor samples indicative of the state of the industrial automation process to determine a second control trajectory of the plurality of input variables of the industrial automation process when the first control trajectory is not feasible;
• and
• control, using the processing circuitry, performance of the industrial automation process at least in part by:
• instructing one or more actuators to perform a first control action determined based on the first control trajectory when the first control trajectory is feasible;
• and
• instructing the one or more actuators to perform a second control action determined based on the second control trajectory when the first control trajectory is not feasible.
