An optimal strategy based on minimum effort control and also with terminal positionconstraint is developed for an exoatmospheric interceptor with a fixed- interval guidance time. It isthen integrated with sliding-mode control theory to drive an optimal sliding-mode guidance law forfixed-interval guidance time. In addition, this guidance law is generalized for intercepting anarbitrarily time-var...

This paper investigates the robust ∞ H sliding mode control problem for a class of uncertain switched delay systems. A single sliding surface is constructed such that the reduced-order equivalent sliding motion restricted to the sliding surface is completely invariant to all admissible uncertainties. For cases of known delay and unknown delay, the existence conditions of the sliding surface are...

in this paper, we discuss the dynamical properties of a chemical reactor model including lyapunov exponents, bifurcation, stability of equilibrium and chaotic attractors as well as necessary conditions for this system to generate chaos. we study the synchronization of chemical reactors model via sliding mode control scheme. the stability of proposed method is proved by barbalate’s lemma. numeri...

A simple method for the initial synchronization in a spread spectrum receiver using the sliding method is proposed. The method is based on the examination of the slope of the correlation function between the spreading sequence of the receiver and that included in the received signal. It is proved that the slope is related to the phase difference of the above mentioned sequences and its knowledg...

In this paper we propose an online Wavelet Discrete Transform implementation scheme. Our proposal improves the execution time compared to the traditional sliding window method. Also, we modify the definition of the data window concept given in the original scheme. The experiments we performed show that the runtime cost of the proposed algorithm is better than that of the traditional sliding win...

In this paper, a novel method for the establishment of a sliding mode in a nonlinear system is presented. The method discussed aims to minimize a cost measure, which is a function of the switching sugace. For this purpose, an adaptive fuzzy controller is selected and the parameters of the defuuifier are adjusted such that the cost is minimized and the system is enforced to behave in sliding mod...

Abstract This paper studies the robust optimal control problem for robot tracking system. An optimal sliding mode control law is designed to solve this problem. Integral sliding mode control is employed to combine the first-order sliding mode with optimal control approach and is applied to robust control of robot manipulators. For the optimal control part, the Lyapunov optimizing control method...

Original scientific paper A method for practical implementation of discrete-time sliding mode control technique for control of plants with stable finite zero is proposed in this paper. The method is based on a combination of different conventional and sliding mode control approaches. The control system contains a sliding mode controller, an observer, based on nominal plant model without finite ...
