Linear control laws for singular linear systems [PDF]
Journal of the Franklin Institute, 1964 Abstract For a class of quadratic performance indices the optimal control law is a combination of maximum effort (bang-bang) and singular. The singular control law is linear and it is optimal in a hyperplane in the n-dimensional state-space. For practical purposes it is desirable to restrict the class of admissible control laws to be linear.

Perturbation of linear control systems
Linear Algebra and its Applications, 1989 AbstractWe study the variation of the controllability indices and the Jordan structure of a pair of matrices (A, B), under small perturbations.

Covertly Controlling a Linear System
IEEE Transactions on Information Forensics and Security, 2022 Consider the problem of covertly controlling a linear system. In this problem, Alice desires to control (stabilize or change the parameters of) a linear system, while keeping an observer, Willie, unable to decide if the system is indeed being controlled or not. We formally define the problem, under two different models: (i) When Willie can only observe

On local linearization of control systems [PDF]
Journal of Dynamical and Control Systems, 2009 We consider the problem of topological linearization of smooth (C infinity or real analytic) control systems, i.e. of their local equivalence to a linear controllable system via point-wise transformations on the state and the control (static feedback transformations) that are topological but not necessarily differentiable.

Controllability and null controllability of linear systems [PDF]
Journal of Applied Sciences and Environmental Management, 2006 This paper establishes sufficient conditions for the controllability and null controllability of linear systems. The aim is to use the variation of constant formula to deduce our controllability grammiam, by exploiting the properties of the grammiam and the asymptotic stability of the free system, we achieved our results.

Risk‐aware self‐triggered linear quadratic control
IET Control Theory & Applications, 2023 This paper presents a self‐triggered control approach with the view of risks for discrete‐time linear stochastic systems. More specifically, under the assumption that the first two moments of the disturbance distribution are known, the paper considers ...

An online intelligent robust adaptive LSQR estimation method for LTI state space model
IET Control Theory & Applications, 2023 Regarding the low accuracy and instability of common online methods for estimating dynamic models in the time domain, in the presence of uncertainty in system dynamics, sensor noise and environmental disturbances, this area is still open for further ...

A note on the minimum‐norm in dual space approach to some classical linear optimal control problems
The Journal of Engineering, 2023 Some classical optimal control problems of linear systems can be characterized as finding minimum‐norm vectors from within linear varieties in appropriate dual spaces.
