Reference and command governors are add-on control schemes which enforce state and
control constraints on pre-stabilized systems by modifying, whenever necessary, the …

This paper provides a tutorial overview of reference governors and command governors,
which are add-on control schemes for reference supervision and constraint enforcement in …

Reference governors are applied to closed‐loop tracking systems that are linear and
discrete time and have constraints on state and control variables. Earlier results are …

This paper proposes a new approach to reference governor design. As in prior literature, the
governor accepts input commands and modifies their evolution so that specified pointwise-in …

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 …

This paper considers a nonlinear feedback control policy that is an extension of those
provided by command governors and reference governors. As in these control approaches it …

This paper 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 …

This technical note introduces a novel control law that dynamically modifies the reference of
a pre-compensated nonlinear system to ensure the satisfaction of constraints. This is done …

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 …

A method based on conceptual tools of predictive control is described for solving set-point
tracking problems wherein pointwise-in-time input and/or state inequality constraints are …
