TL;DR: This paper addresses a new approach, called the optimal path estimation method (OPEM), to implement the time optimal bang-bang control, based on feedback information obtained by estimating the distance from the present state to the switching surface along the optimal trajectory.
Abstract: This paper addresses a new approach, called the optimal path estimation method (OPEM), to implement the time optimal bang-bang control. The method is based on feedback information obtained by estimating the distance from the present state to the switching surface along the optimal trajectory. A fuzzy algorithm is used for the implementation of the control logic. Advantages of the proposed method over traditional bang-bang control method are illustrated by numerical simulations of a multimachine infinite-bus power system.

TL;DR: A set-valued time derivative is introduced for nonsmooth function along discontinuous vector fields, which enables us to perform Lyapunov-based design with non-regular LyAPunov function for the Fillipov solutions.
Abstract: This paper investigates the feedback stabilization problems for a class of discontinuous nonlinear systems. A set-valued time derivative is introduced for nonsmooth function along discontinuous vector fields, which enables us to perform Lyapunov-based design with non-regular Lyapunov function for the Fillipov solutions. The first result is to give a design approach to a discontinuous feedback control law for a class of nonlinear systems under a matched discontinuity. Then, it is shown that the control law, as virtual control, can be extended to recursive design problem when the control input is provided by an integrator. Numerical example is given to illustrate the design approach.

TL;DR: In this paper, a robust finite-time output regulation problem for linear and nonlinear systems driven by exosystems with uncertain disturbances is studied. But unlike most of the existing results, the exos system is nonautonomous and involves bounded unmodeled uncertainties.
Abstract: In this paper we deal with robust finite-time output regulation problem for linear and nonlinear systems driven by exosystems with uncertain disturbances. Unlike most of the existing results, the exosystem is nonautonomous and involves bounded unmodeled uncertainties. A design method of variable structure controller is presented and it is shown that the global robust finite-time output regulation can be achieved. Illustrative example is shown to demonstrate the efficiency of the proposed approach.

TL;DR: In this article, a shunt three phase active power filter with reference values based on p-q theory, using sliding mode control, is presented, where the nonlinear load is composed either of a capacitive and an inductive component, or just inductive components.
Abstract: In this paper a shunt three phase active power filter with reference values based on p-q theory, using sliding mode control, is presented. The nonlinear load is composed either of a capacitive and an inductive, or just an inductive component. The filter is analyzed and the mathematical model of the inverter, the state equations of the power system, the sliding mode control with the existence conditions and the stability of the system are determined. For the realization of sliding mode control of the three-phase inverter connected in parallel, when the nonlinear load has a capacitive component, a compensating capacitor is needed, parallel with the active filter. The reference values for the filter are obtained using the instantaneous real and imaginary power theory. The expected results are confirmed by experimentations.

TL;DR: This paper presents an algorithm for adaptively controlling nonlinear single-input single-output, minimum phase systems with relative degree one which are linear with respect to input and unknown constant parameter vector.
Abstract: This paper presents an algorithm for adaptively controlling nonlinear single-input single-output, minimum phase systems with relative degree one which are linear with respect to input and unknown constant parameter vector. The algorithm does not require the knowledge of the sign of high frequency gains and measurement of states.
