Distributed LQR-based Suboptimal Control for Coupled Linear Systems

Stochastic Mixed LQR/H∞ Control for Linear Discrete-Time Systems

Suboptimal Event-based Control of Linear Systems over Lossy Channels ⋆

The emergence of networked control systems urges the joint consideration of control and communications. It is well known that event-based controllers outperform standard timetriggered designs, when the transmission rate is constrained. This paper considers the design of suboptimal event-based controllers in the presence of packet loss and delayed acknowledgement for linear stochastic systems. T...

a new type-ii fuzzy logic based controller for non-linear dynamical systems with application to 3-psp parallel robot

abstract type-ii fuzzy logic has shown its superiority over traditional fuzzy logic when dealing with uncertainty. type-ii fuzzy logic controllers are however newer and more promising approaches that have been recently applied to various fields due to their significant contribution especially when the noise (as an important instance of uncertainty) emerges. during the design of type- i fuz...

Performance of suboptimal linear control systems

I t is shown that the calculation of the performance of a class of suboptimal linear control systems is similar to the calculation of the performance of an equivalent optimal system. The performances of both optimal and suboptimal linear systems have terms for cost owing to uncertainty about the initial state of the plant, a nonzero mean of the initial state, error in the estimate of the state,...

LQR-based coupling gain for synchronization of linear systems

Synchronization control of coupled continuous-time linear systems is studied. For identical systems that are stabilizable, a linear feedback law obtained via algebraic Riccati equation is shown to synchronize any fixed directed network of any number of coupled systems provided that the coupling is strong enough. The strength of coupling is determined by the smallest distance of a nonzero eigenv...
