High Speed Rotating Mechanism Control And Semi-physical Simulation

The development of science and technology has raised people's demand for material civilization,and the demand for weapons has also changed from high-killing weapons to high-precision weapons.Two-dimensional correction technology is able to improve the accuracy of projectile hit,so received the attention of various countries.In the process of studying the two-dimensional correction projectile,on the one hand,it is difficult to control,low control accuracy,on the other hand,high cost and difficult to observe the phenomenon of target test and other issues difficult to solve.In order to solve this problem,this paper analyzes and designs the high-speed rotating mechanism used in modified fuze based on the basic principle of trajectory correction.The design of the high speed rotating motor and the output control of the motor torque are analyzed emphatically.The high-speed rotary steering gear used in the two-dimensional correction projectile is analyzed,obtained the control scheme of the motor according to the force condition.Focus analysis the motor control method and torque characteristics.According to experimental principle,the control algorithm is experimentally verified.This paper is mainly applied to the High-speed rotating mechanism's design and control of fuze correction.Analysis of the overall structure and basic layout Correction fuze.The model establishment and detailed force analysis are carried out for the high-speed rotation correction servo.Design and analysis of basic motor control schemes for high-speed rotating motors for control systems.The control principle of the steering gear and the torque situation are analyzed,And analyzes and calculates the torque of the canards,and the corresponding motor torque calculation.According to the force of the steering gear to measure and solve the motor torque output with the difference speed and PWM.The control time of the servo is calculated according to the mechanical dynamics,applying geomagnetism to measure the roll angle of a projectile,The sensor is combined with the geomagnetism to calculate the servo roll angle relative to the ground,calculate the duty cycle output of the torque motor by experiment.And according to the correction process of amendments to write control procedures,the high-speed rotation mechanism is controlled by the simulation experiment device.Detected the torque output and the angle control of the steering gear and verified the feasibility of the control algorithm.
