The paper discusses the H∞ preview control problem. We apply simple tools such as completion of square to solve the problem. The sufficient and necessary condition under which the finite-horizon problem is solvable is provided and is actually the inertia condition reflecting the aftereffect from the disturbance. Different from existing results, the proposed controller is given by a Riccati equation...
To hire multiple agents cooperating to solve realworld problem with large state space, a precondition is to provide an interaction medium for knowledge exchange and share among agents. We propose an interaction medium: State-Clusters, computed from the state trajectory that the agent wandered in state space. The State-Clusters of a state includes acyclic state paths from other states to this state,...
This paper investigates the stability of switched linear systems with the perturbed switching. In premises of introducing the notions of common child-path and parent-path, we define distance between switching paths. A constructive procedure is proposed for finding common child-paths, then we reveal a relationship between common child-path and parent-path, and subsequently formulate the distance. Finally,...
In this paper, the problem of Hinfin control for a class of Markov jump linear system (MJLS) with timevarying transition rates (TRs) is investigated. The time-varying character of TRs is considered as finite piecewise homogeneous and the variations of TR matrices in the finite set are considered as two types: arbitrary variation and stochastic variation. The latter means that the variations are subject...
In this paper we develop a general discrete-time adaptive control approach suitable for nonlinear systems with periodic parametric uncertainties. The underlying idea of the new approach is to convert the periodic parameters into an augmented constant parametric vector by a lifting technique. As such, the well-established discrete-time adaptive control schemes can be easily applied to various control...
Structural controllability evaluation for heat exchanger networks (HENs) was proposed in this paper. Structural singularities, right-half plane zeros, time delays, and interactions were considered as structural analysis tools, in which the evaluation was formulated as an integer linear programming (ILP). The solutions comprising of the number of parallel opposing effects, the sum of relative orders,...
The online computation efficiency is always an important issue of the robust model predictive control (RMPC), especially for fast systems. For uncertain systems with polytopic description, two synthesis approaches of off-line RMPC are presented. By offline designing several polyhedral invariant sets properly, the online computation of RMPC is only simple algebra calculation, which reduces the online...
Parametric optimization techniques is an established practice for designing controllers. It was used, for example, to obtain the parameters of PI and PID controllers in several works. An important criticism to this technique is the dependence of the design from a parametric model of the plant, which have to be very accurate. In the current work, the problem of designing a continuous-time PID controller...
