In this paper, a model free based sliding mode control (MFSMC) is developed to realize the attitude control of a quadrotor whose model contains the system uncertainties and external disturbances. Firstly, a model free based intelligent PD controller (iPD) which contains time-delay estimation is designed. The problem is that although the proposed design of(More)
In this paper, a nonlinear observer based sliding mode control (NOSMC) approach for air-path in the diesel engine equipped with a variable geometry turbocharger (VGT) and exhaust gas recirculation (EGR) is introduced. We propose a less conservative observer design technique for Lipschitz nonlinear systems using Ricatti equations, which works for(More)
— In this paper, a fourth-order dimensional non-linear model is proposed for a diesel engine equipped with a Variable Geometry Turbocharger (VGT) and an Exhaust Gas Recirculation (EGR) valve. The referred model which takes into account the engine crankshaft speed dynamics and the air-path dynamics is a non-minimum phase unstable system. The fuel flow rate W(More)
In this paper modeling and common-rail pressure control of high pressure common rail injection system (HPCRIS) is presented. The proposed mathematical model of high pressure common rail injection system which contains three sub-systems: high pressure pump sub-model, common rail sub-model and injector sub-model is a relative complicated nonlinear system. The(More)
The interaction free energy per unit area between parallel flat plates with high surface potential in the case of constant surface potential is again presented. It is complementarity for extended Langmuir method [G. Luo, H. Wang, J. Jin, Langmuir 17 (2001) 2167 and G. Luo, R. Feng, J. Jin, H. Wang, J. Colloid Interface Sci. 241 (2001) 81]. These approximate(More)
The paper deals with the recursive model free control of horizontal variable speed wind turbines, which makes possible to obtain a compromise between the wind energy limitation, the rotor speed reference tracking and the decreasing of solicitations induced in the mechanical structure of the turbine. The wind turbine system dynamics is described by a(More)
On the basis of Langmuir's suggestion we simplify the Poisson-Boltzmann equation and derive the relation of surface potential, potential midway, and the plate distance. Thus we obtain the interaction force and energy equations between two dissimilar plates in the case of constant surface charge density. Agreement with the exact numerical values of the(More)
