Difficulties in achieving the maximum level of efficiency in power extraction from available wind resources warrant the collective attention of modern control and power systems engineers. A strong movement towards sustainable energy resources, and advances in control system methodologies, make previously unattainable levels of efficiency possible. One such promising method is sliding mode control...
For the aerodynamic parameters identification of projectile and rocket under the influence of random wind, based on the control system sensitivity theory, the formation of the sensitivity and related mathematical models according to realistic systems are formulated. Sensitivity principle of the control system theory is applied to the identification of resistance coefficient. Analyzing missile system...
Three-dimensional unsteady Reynolds averaged incompressible Navier-Stokes equations are used to simulate the aerodynamic performance of a horizontal axis wind turbine. The numerical method that adopted in this paper is proved to be effective to predict horizontal axis wind turbine aerodynamic characteristics by contrasting the numerical results to the wind turbine experimental data. And the curve...
Trajectory correction fuze is the integrated guidance and control and the new fuze technology which can correct trajectory through the fuze. In order to improve solution precision for trajectory correction fuze, a resistance coefficient identification method based on the sensitivity theory of control system is put forward. Combined with test data of the ballistic parameters, resistance coefficient...
Random wind is one of the important factors causing rocket fall points distribution. For the large and complex system, it is difficult to analyze the reliability using the analytic methods, but the computer simulation is an effective way. In this paper, simulation for flight control system is studied in detail by considering wind as typical random process. The engineered model of wind is established...
The ramjet is a new type propulsion system for high-speed flight test aircraft. The ultimate success of sustained high-speed flight will depend on configuring a fine and stable attitude flight control and robust airframe-propulsion-control combination. The mathematical models of high-speed aerodynamic forces and moments were established. A bank-to-turn autopilot structure was used for the longitudinal...
This paper deals with a problem of turbine engine fault detection in dynamic process by using LPV mathematical model to exactly describe turbine engine dynamic characteristics, eliminate the effects of modeling error. Design robust fault detection filter (FDF) with eigenstructure assignment and realizes disturbance de-coupled with model uncertainty. The simulation results of turbine engine control...
