A method controls an operation of a laser processing machine with redundant actuators including a first actuator and a second actuator. The method determines a feasible region for states of the first actuator and states of a reference trajectory of the first actuator defined by constraints of the laser processing machine, constraints on the reference trajectory and constraints on a range of motion of the second actuator. The method selects a subset of the feasible region, such that for any state of the first actuator and any state of the reference trajectory within the subset, there is an admissible control maintaining the state of the first actuator within the subset of the feasible region for admissible future states of the reference trajectory, and selects an admissible control action for controlling the operation such that the state of the first actuator remains in the subset of the feasible region.
A method for controlling an operation of a laser processing machine with redundant actuators including a first actuator and a second actuator, comprising:
A controller for controlling an operation of a first actuator of a laser processing machine according to a reference trajectory by selecting a control action for controlling the operation such that a state of the first actuator for admissible future states of the reference trajectory remains in a subset of the feasible region of states of the first actuator and states of the reference trajectory, wherein the feasible region is defined by constraints of the first actuator, constraints on the reference trajectory and constraints on a range of motion of a second actuator of the laser processing machine, and wherein the subset of the feasible region is a control invariant, such that for any state of the first actuator within the subset, there is a control maintaining the state of the first actuator within the subset for all admissible future states of the reference trajectory.
A method for controlling an operation of a laser processing machine according to a processing pattern, wherein the laser processing machine includes a first actuator and a second actuator, comprising:
