ROBUST MULTIVARIABLE SET-POINT REGULATION VIA STABLE DYNAMIC INVERSION

Robust Multivariable Set-point Regulation via Stable Dynamic Inversion

In this paper we propose a design methodology for the robust regulation of uncertain nonminimum-phase multivariable linear systems. The method basically consists of defining a suitable vector of parameterized desired output functions and of designing a parameterized decoupling controller of the nominal plant. Then, a parameterized command function for each input is determined by means of a stab...

Optimal Nonzero Set Point Regulation Via Fixed - Order Dynamic Compensation

Standard LQG control theory is generalized to a regulation problem involving specified nonzero set points for the state and control variables and nonzero-mean disturbances. For generality, the results are obtained for the problem of fixed-order (i.e., not necessarily full-order) dynamic compensation. When the state, control, and disturbance offsets are set to zero and the compensator order is s...

Dynamic inversion for multivariable non-affine-in-control systems via time-scale separation

Robust inversion of non-linear dynamic systems

Weight reduction is becoming increasingly important in products that undergo cyclic loading, such as cars, aeroplanes, wind turbines, etc. The novelty of these dramatic design changes will cause material fatigue to become one of the key design drivers in the development of cars, aeroplanes, wind turbines and require tools to accurately predict the life time of a construction. The life time can ...

Optimal inversion-based control for the set-point regulation of nonminimum-phase uncertain scalar systems

In this note,1 we propose an optimal inversion-based control for the set-point constrained regulation of nonminimum-phase uncertain scalar systems. This approach is based on a new control architecture where the main purpose of the feedback is to reduce the sensitivity to parametric plant uncertainties permitting in such a way the effective use of a feedforward action determined via a stable dyn...
