Simulation Research Of Pitch Control Machine On Variable Vector Propeller

The Variable Vector Propeller (VVP) , as new kind impellent equipment, is still at the stage of R&D. It has broken the conventional pattern of propeller operating controllers that has some propellers. Effectively solve the problems of conventional propellers that has bad structure continuity, low intensity, the high criterion requests (for example pressure resistance shell thickness), limit internal arrangement, big power loss etc. The WP has the broad project practical prospect. This article mainly in view of pitch control machine on the WP.Firstly, the positive kinematics and the inverse kinematics model of pitch control machine on the WP are detruded. And in infers in numerical solution foundation, optimized simulation is carried on to the positive kinematics of the pitch control machine on the WP by using genetic algorithm neural network.Secondly, dynamics mathematical model is built up by using the Lagrange equation method and Kane equation method. Singularity analysis judgment is finished by the method of using Genetic Algorithm(GA) optimize solves minimum value of Jacobin matrix.Afterward, mathematical model of electro-hydraulic servo is built up. GA is designed to improve the compatibility of PID controller. Simulation research has conducted by using MATLAB. The result indicated that the GA-PID controller has higher course control precision, better robust performance.Finally, the Virtual Prototype Technology(VPT) is used in the analysis and the experiments of pitch control machine on the WP. Analysis and proof of the dynamics and the kinematics of the machine is done by using ADAMS. Obtains various components' state of motion through the simulation. Interactive carries on the design parameter the adjustment and the improvement. Provide the data reference to the WP's posture adjustment. Has provided the reliable guarantee for the entity prototype's development.
