Abstract:
We consider a dual-stage precision manufacturing machine where a worktool is actuated via a motion system consisting of a "fast" stage with large bandwidth but small operating range, and a "slow" stage with smaller bandwidth but larger operating range. We design a controller based on a recently developed tracking method for constrained systems that guarantees enforcement of constraints and of an assigned bound on the tracking error. For satisfying the controller assumption, we design a reference trajectory generation algorithm that is simple and can also be executed offline. The proposed control system guarantees correct processing of the pattern and finite processing time, for which bounds can be easily computed.

Research Areas: Control, Dynamical Systems, Machine LearningBrief- The premier American Control Conference (ACC) takes place in Boston July 6-8. This year MERL researchers will present a record 20 papers(!) at ACC, with several contributions, especially in autonomous vehicle path planning and in Model Predictive Control (MPC) theory and applications, including manufacturing machines, electric motors, satellite station keeping, and HVAC. Other important themes developed in MERL's presentations concern adaptation, learning, and optimization in control systems.
