Title Design And Simulation On Controller Of Vertical Overload Of Artillery Missile
Abstract
Artillery missile is the combination of precision-guided systems and conventional artillery systems. In this way, not only retain the original system’s fast response and fierce fire, but also increase the long-range of resistance capability and the accuracy of the missile. Artillery missiles are a high-tech projectile. It give long-range precision strike capability to the indirect targeting anti-personnel weapons and becomes the focus of the weapons-research.It is the Guidance technology on the missile makes that artillery missiles have a strong anti-interference against the external natural factors, thereby increasing the hit probability and the killing effect of the projectile.
Overload control technology is used to design artillery missile autopilot instrument. Newtonian mechanics is used to build a vehicle dynamics model. "Disturbance" is the linear model’s assuming. Above all, a mathematical model of the control loop based on the aircraft overload can be established.Overload tracking control loop is designed by PID, and a simulation is completed. The simulation results show that the rise time is less than 0.1 seconds, the overshoot is less than 10% and the tracking error is less than 5 %. The overload tracking control loop suffices the performance indicators.
