Robust synchronization of two hyperchaotic Wang systems is investigated in this paper, using sliding method. In the sliding mode control algorithm, two different sliding surfaces are defined to both stabilize the synchronization error dynamic and guarantee the prescribed disturbance attenuation. The stability of the system is proven using Lyapunov stability theory. Simulation results confirm the high...
The problem of synchronization for fractional master-slave Lorenz chaotic systems coupled with sector nonlinear control input is investigated. Using the sliding mode control technique, a control scheme containing a new fraction-integer integral (FII) switching surface is developed to guarantee the synchronization of fractional Lorenz chaotic systems even when the sector nonlinearity is present. Numerical...
In this paper the quadrotor dynamic model with nonlinear inputs is presented. Deadzone and saturation nonlinear inputs are considered for the quadrotor reflected to the actuators. The goal is to obtain a faithful mathematical representation of the mechanical system for system analysis and control design, not only in hover as presented in many works, but also in motion when take-off, land and flight...
This paper presents a systematic methodology for developing structural macromodels expressing the linear and weakly nonlinear performance of analog circuits. The models are in the frequency domain. The methodology includes two steps. First, building-block behavioral (BBB) concept is used to describe the basic building blocks of a circuit, and a decoupling technique is used to generate uncoupled BBB...
