In this paper, reference and extended command governors are developed for enforcing constraints in the air path of turbo-charged gasoline engines. These governors are add-on control schemes which protect the engine from violating pointwise-in-time state and control constraints, including compressor surge and actuator limits. Several design choices based on(More)
We develop nonlinear reference governor and nonlinear model predictive control schemes for constrained spacecraft attitude control. The schemes use the nonlinear discrete-time model of spacecraft dynamics based on the Lie group variational integrator evolving on SO(3) x SO(3). The reference governor is a computationally simpler add-on to the nominal(More)
