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

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.

Coordination of multi‐agent systems with arbitrary convergence time
IET Control Theory & Applications, 2021 This paper proposes fixed‐time solutions to several problems in multi‐agent systems. First, a fixed‐time consensus protocol is investigated and under the assumption that the lower bound of smallest positive eigenvalue of the Laplacian matrix is known in ...

Molecular Oncology, EarlyView.Combining PTEN protein assessment and transcriptomic profiling of prostate tumors, we uncovered a network enriched in senescence and extracellular matrix (ECM) programs associated with PTEN loss and conserved in a mouse model. We show that PTEN‐deficient cells trigger paracrine remodeling of the surrounding stroma and this information could help ...
