<p style='text-indent:20px;'>The paradigm of discounting future costs is a common feature economic applications optimal control. In this paper, we provide several results for such discounted control aimed at replicating the now well-known in standard, undiscounted, setting whereby (strict) dissipativity, turnpike properties, and near-optimality closed-loop systems using model predictive a...

The discrete-time robust repetitive control (RC, or repetitive controller, also designated RC) problem for nonlinear systems is both challenging and practical. This paper proposes a discrete-time output-feedback RC design for a class of systems subject to measurable nonlinearities to track reference robustly with respect to the period variation. The design relies on additive state decomposition...

These days, networked control systems (NCSs) in which data is transmitted via communication have been actively studied for many potential applications. In an NCS, dropout degrades performance depending on network conditions. For NCS with dropout, the authors propose a model-predictive-control-based input optimisation, representing as both Bernoulli model and finite-order Markov chain. Using pro...

This paper studies distributed control of multi-vehicle formations with angle constraints using bearingonlymeasurements. It is assumed that each vehicle can onlymeasure the local bearings of their neighbors and there are no wireless communications among the vehicles. The desired formation is a cyclic one, whose underlying information flow is described by an undirected cycle graph. We propose a ...

We consider the problem of determining an optimal driving strategy in a train control problem with a generalised equation of motion. We assume that the journey must be completed within a given time and seek a strategy that minimises fuel consumption. On the one hand we consider the case where continuous control can be used and on the other hand we consider the case where only discrete control i...

In the control systems literature, it is well known that a separation principle holds locally for nonlinear control systems, when exponential feedback stabilizers and exponential observers are used. In this paper, we present a counterexample to show that the global separation principle need not hold for nonlinear control systems. Our example demonstrates that global stability might be lost when...

This paper is concerned with uncertain systems subject to periodic disturbances with a known period, and the discrete-time variable structure repetitive control methodology is applied to address the control problem. The notion of quasisliding mode is reviewed in this paper. Switching-function dynamics obtained with the proposed repetitive strategies are desirable, which govern both reaching pha...
