| 1 | Finite time convergent control using terminal sliding mode显示文摘A method for terminal sliding mode control design is discussed. As we know, one of the strong points of terminal sliding mode control is its finite-time convergence to a given equilibrium of the system under consideration, which may be useful in specific applications. The proposed method, different from many existing terminal sliding model control design methods, is studied, and then feedback laws are designed for a class of nonlinear systems, along with illustrative examples. | YiguangHONG GuowuYANG DaizhanCHENG SarahSPURGEON | 2004 | 控制理论与应用(英文版)2004，2，1： | 11 |
| 2 | A note on overshoot estimation in pole placements显示文摘In this note we show that for a given controllable pair ( A, B ) and any λ> 0, a gain matrix K can be chosen so that the transition matrix e(A+BK)t of the system x = (A + BK)x decays at the exponential rate e-λt and the overshoot of the transition matrix can be bounded by MλL for some constants M and L that are independent ofλ. As a consequence, for any h >0, a gain matrix K can be chosen so that the magnitude of the transition matrix e(A+BK)t can be reduced by -1/2- (orby anygivenportion) over [0, h ] . An interesting applicafon of the result is in the stabilization of switched linear systems with any given switching rate ( see [ 1 ] ). | DaizhanCHENG LeiGUO YuandanLIN YuanWANG | 2004 | 控制理论与应用(英文版)2004，2，2： | 5 |
| 3 | APPROXIMATE OUTPUT REGULATION FOR AFFINE NONLINEAR SYSTEMS显示文摘Output regulation for affine nonlinear systems driven by an exogenous signal is investigated in this paper. In the absence of the standard exosystem hypothesis, we assume availability of the instantaneous values of the exogenous signal and its first time-derivative for use in the control law.For affine nonlinear systems, the necessary and sufficient conditions of the solvability of approximate output regulation problem are obtained. The precise form of the control law is presented under some suitable assumptions. | YaliDONG DaizhanCHENG HuashuQIN | 2003 | Systems Science and Systems Engineering2003，12，4： | 0 |
| 4 | Optimization leads to symmetry显示文摘The science of complexity studies the behavior and properties of complex systems in nature and human society.Particular interest has been put on their certain simple common properties.Symmetry is one of such properties.Symmetric phenomena can be found in many complex systems.The purpose of this paper is to reveal the internal reason of the symmetry.Using some physical systems and geometric objects,the paper shows that many symmetries are caused by optimization under certain criteria.It has also been revealed that an evolutional process may lead to symmetry. | ChenghongWANG YuqianGUO DaizhanCHENG | 2004 | 控制理论与应用(英文版)2004，2，4： | 0 |
