基于舵机俯仰姿态控制回路的电视制导设计

Design of the Television-guided Based on Actuation Pitch Attitude Control Loop of Servo System

设计了舵机系统的俯仰姿态控制回路,并通过舵偏角的改变来说明电视制导系统的设计理念。首先,通过建立导弹的运动学模型,选择适当的旋转变压器和减速器,并采用三点导引法完成了电视制导系统的设计。然后,根据数学模型计算出各个环节中的传递函数,采用simulink软件仿真,通过适当的改变参数,并采用积分环节进行校正,实现电视制导的控制系统。最后,通过对电视制导控制系统建模和仿真,并对系统输出产生的误差进行相关说明,提出改进意见。

The paper designs a control loop of actuation pitch attitude in Servo System, only through changing the rudder angle to illustrate the design concepts of television guidance system. Through the establishment of the missile＇s kinematic model, selecting the appropriate resolver and reducer, and adopting three-point guidance method to complete the television guidance system. To calculate every aspect of the transfer function basing on the establishment of a mathematical model.Applying simulink-soflware simulation, changing parameters appropriately and calibrating using integral part, to achieve television-guided control system. According to the modeling and simulation of the television-guided control system, to analysis outout error on the system and suggest the imorovements.
