Missile Launching Vehicle Follow-up System Project Optimization Research

According to the conventional configuration of air-ground tactical weapon systems,the missile launching vehicle has become the focus of tactical weapons research topic.As the main combat vehicle weapon system,the missile launching vehicle gives the control commands,parameters transmission before launching and dynamic aims target position before the launch of the missile.The research object of this thesis is a missile launching vehicle which is a completed production and has been supplied to troops.Before this research,the launching vehicles have a lot of problems when they being used in the troops,such as CPU crashes(EMI problem),launcher drift(electric motor problem),crawling and tremor in tracking process(control problem),poor maintainability(frame structure problem)and low reliability(component problem).In this thesis,following aspects are studied.1?The hardware optimization selection of follow-up system is studied.The current detection circuit has been redesigned to decrease the high false alarm rate.The design of power module has been revised to solve the problem of multiple failure.An advanced design has been proposed to solve the problem that the servo system does not adapt to the harsh environment and the special conditions in the engineering.2?The optimization design of control software is studied.To solve the problems in the former control scheme,this paper proposes a servo control mode based on fuzzy PID control theory to replace the traditional PID control algorithm.This servo control mode reconstructs the servo system equipment,chooses the servo motor according to the servo system load and working conditions.The validity of the control mode has been presented by the theory analysis and simulation results.3?The improvement of electromagnetic compatibility is researched.The ability to resist electromagnetic interference of the former follow-up system is weak,which will result in CPU crashes,launcher drift and other problems.Therefore the EMC of missile launch vehicle has been improved.The verification and validation has been demonstrated by tests.In this thesis,a optimization method for old weapon equipment follow-up system is formed besides the optimized missile launching vehicle,and a specific example is provided for follow-up system design and engineering.
