This paper considers the robust output regulation problem for nonlinear time-varying systems with a time-varying exosystem. A framework for converting the problem into a stabilization problem of an augmented system is established. The problem is solved for a class of time-varying output feedback systems with a time-varying exosystem.
For the time series prediction problem, the relationship between the abstracted independent variables and the response variable is usually strong non-linear. We propose a neural network fusion model based on k-hyperpl...

In this paper, the problem of dissipativity analysis and output feedback control synthesis for discrete linear time-invariant systems with state-space symmetry is investigated. Firstly, an explicit expression of H∞ norm for discrete-time symmetric system is given under the mixed H ∞ and positive real performance criterion, and this is a particular case of dissipative systems. Subsequently, we consider the control synthesis problems for such systems and obtain an explicit parameterized expression of the static output feedback controllers. Finally, two numerical examples are employed to show the effectiveness and reliableness of the proposed approach.

This paper deals with the robust control problem for a class of uncertain nonlinear networked systems with stochastic communication delays via sliding mode conception （SMC）. A sequence of variables obeying Bernoulli distribution are employed to model the randomly occurring communication delays which could be different for different state variables. A discrete switching function that is different from those in the existing literature is first proposed. Then, expressed as the feasibility of a linear matrix inequality （LMI） with an equality constraint, sufficient conditions are derived in order to ensure the globally mean-square asymptotic stability of the system dynamics on the sliding surface. A discrete-time SMC controller is then synthesized to guarantee the discrete-time sliding mode reaching condition with the specified sliding surface. Finally, a simulation example is given to show the effectiveness of the proposed method.

This paper describes a robust controller design procedure based on H ∞ control theory for translational mechatronic system, trolley with pendulum. The goal is to achieve fast trolley positioning with minimization of pendulum swinging. This system, trolley with pendulum, represents gantry crane. Minimization of the load transfer time and load swing angle in the crane applications are conflicting control demands and thus proper control action is required. However, friction effect is unavoidable in mechanical parts of the system and significantly influences the control system performances. In this paper H ∞ theory based crane controller is designed in order to minimize friction effect. H ∞ controller has been tested and compared with the pole placement controller on a laboratory gantry crane model.

A variety of problems in digital circuits, computer networks, automated manufacturing plants, etc., can be modeled as min-max systems. The cycle time is an important performance metric of such systems. In this paper, we focus on the cycle time assignment of minimax systems which corresponds to the pole assignment problem in traditional linear control systems. For the min- max system with max-plus inputs and outputs, we show that the cycle time can be assigned disjointedly by a state feedback, if and only if the system is reachable. Furthermore, a necessary and sufficient condition for the cycle time to be assigned independently by a state feedback is given. The methods are constructive, and some numerical examples are given to illustrate how the methods work in practice.
