The main contributions of this paper are twofold: (1) the concept of finite-time stability for polynomial fuzzy model is firstly proposed, and (2) finite-time stabilizing controller is designed to stabilize the nonlinear system represented in the form of SOS, which is superior to the form of LMIs.

In particular, it has been shown that a TS dynamic model obtained through the nonlinear sector transformation approach can describe the overall behavior of a highly complex nonlinear system with a high degree of accuracy [11, 14].
SDRE is a nonlinear system control method proposed in the 90s of last century.
With the developing of nonlinear system theories, expanding the scope of delayed systems to nonlinear systems has aroused great interests.
In order to demonstrate the position control enhancement for the nonlinear system, the proposed controller is compared with classical PID controller using simulation results with and without external disturbance.
In the past decade, control and synchronization of nonlinear system in industry have attracted much attention.
Because dropping shock is one of the main factors that cause the mechanical damage of most packaged products potentially in the transportation, the numerical results of a nonlinear cushioning system were derived by applying Runge-Kutta method and the dropping damage boundary concept of the packaged article was proposed [6], but no research has been conducted on whether the drop equivalent test is still suitable for nonlinear system. Then, some researchers improved the accuracy of a nonlinear system drop test [7,8].
Now we select the state space variables as x = h and u = [q.sub.v] and we obtain the nonlinear system
In general, the goal of the MMP is to compensate a given nonlinear system in order to make its behaviour similar to that of a given nonlinear model.
