Command governors for constrained nonlinear systems
A method is described for set-point tracking in nonlinear systems when pointwise-in-time input and/or state inequality constraints are to be enforced. It consists of adding to a primal compensated system a nonlinear device called command governor (CG) whose action is based on the current state, set-point and prescribed constraints. The CG selects at any time the system input via a receding-hori...
متن کاملCommand Governors for Constrained Nonlinear Systems: Linearization-based Strategies
A comparison between two diierent command governors strategies (CG) is described. A CG is a nonlinear device which is added to a primal compensated system. The CG action, based on the current state, set-point and prescribed constraints, is nalized to select, at any time, a command sequence under which the constraints are possibly fulllled with acceptable tracking performance. The two CG's diier...
متن کاملReference Governor for Constrained Nonlinear Systems
Reference Governor for Constrained Nonlinear Systems Alberto Bemporad Abstract| This note addresses the problem of satisfying pointwise-in-time input and/or state hard constraints in nonlinear control systems. The approach is based on conceptual tools of predictive control and consists of adding to a primal compensated nonlinear system a Reference Governor (RG). This is a discrete-time device w...
متن کاملCommand Governors for Constrained Nonlinear Systems: Direct Nonlinear vs. Linearization-based Strategies
Two command governors (CG) are described for solving set-point tracking problems for nonlinear systems when pointwise-in-time input and/or state related inequality constraints have to be fulllled. A CG is a nonlinear device which is added to a primal compensated system. The CG action, based on the current state, set-point and prescribed constraints, is nalized to select, at any time, a command ...
متن کاملDiscrete-time Reference Governors and the Nonlinear Control of Systems with State and Control Constraints
Discrete-time, linear control systems with specified pointwise-in-time constraints, such as those imposed by actuator saturation, are considered. The constraints are enforced by the addition of a nonlinear ‘reference governor’ that attenuates, when necessary, the input commands. Because the constraints are satisfied, the control system remains linear and undesirable response effects such as ins...
