in this paper, under the existence of system uncertainties, external disturbances, and input nonlinearity, global finite time synchronization between two identical attractors which belong to a class of second-order chaotic nonlinear gyros are achieved by considering a method of continuous smooth second-order sliding mode control (hoamsc). it is proved that the proposed controller is robust to m...

time-delay identification is one of the most important parameters in designing controllers. in the cases where the number of inputs and outputs in a system are more than one, this identification is of great concern. in this paper, a novel autocorrelation-based scheme for the state variable time-delay identification for multi-input multi-output (mimo) system has been presented. this method is ba...

In this paper employing Routh's table, a geometrical stability criterion for the analysis of linear time-invariant system is formulated. The proposed stability criterion is applied for the system, whose characteristic equation having complex coefficients. For this Routh like table is presented with complex terms and the signs pair-wise elements with the first column of the table are observ...

| A new algorithm is proposed for the pole assignment of single-input linear time-invariant systems. The proposed algorithm belongs to the family of Hessenberg methods and is based on an implicit multishift QR-like technique. The new method compares favorably in many respects (speed, memory usage) with existing numerically stable methods. Its improved vectorizability guarantees good opportuniti...

We study the disturbance decoupling problem for linear time invariant singular systems. We give necessary and sufficient conditions for the existence of a solution to the disturbance decoupling problem with or without stability via a proportional and derivative feedback and proportional and derivative output injection that also makes the resulting closed-loop system regular and/or of index at m...

We investigate the exact and approximate spectrum assignment properties associated with realizable output-feedback pole-placement-type controllers for single-input singleoutput linear time-invariant time-delay systems with commensurate point delays. The controller synthesis problem is discussed through the solvability of a set of coupled Diophantine equations of polynomials. An extra complexity...
