A Modified LQG Algorithm (MLQG) for Robust Control of Nonlinear Multivariable Systems [PDF]
Modeling, Identification and Control, 1993 The original LQG algorithm is often characterized for its lack of robustness. This is because in the design of the estimator (Kalman filter) the process disturbance is assumed to be white noise. If the estimator is to give good estimates, the Kalman gain

Multivariable Super-Twisting Algorithm for Systems with Uncertain Input Matrix and Perturbations [PDF]
arXiv, 2021 This paper proposes a Lyapunov approach to the design of a multivariable generalized Super-Twisting algorithm (MGSTA), which is able to control a system with perturbations and uncertain control matrix, both depending on time and the system states. The presented procedure shows that, under reasonable assumptions for the uncertainties, it is always ...

Controlling Multivariable Systems with Significant Uncertainty
IFAC Proceedings Volumes, 1988 Abstract The problem of designing a robust controller for a multivariable system with significant uncertainty is considered. In particular, the class of uncertainty is represented by a set of finite demensional linear time-invariant models of the system.
