机动雷达大惯量天线定位控制策略

Position Control Strategy for Antenna with Great Inertia for Mobile Radar

由于机动雷达大惯量天线的加速度受限,所以在加速度无法提高的前提下,如何减少大惯量天线的转动中定位时间尤为重要。文中提出了一种特殊的机动雷达大惯量天线转动中定位控制策略-分区域定位控制策略,比较了这种控制策略与常规控制方法的优劣,且基于以驱动器为速度内环的控制系统,给出了采用单片机控制的位置环控制电路,并简述了控制软件的实现方法。以实际控制模型为依托、以改善的定位时间为支撑、以简化的定位控制策略为主线,详细介绍了这种新型控制策略的工程运用。

The acceleration of the antenna with great inertia is limited and it can not be improved. Therefore, it is very important how to shorten the location time during the rotation of the antenna with great inertia. A location control strategy for antenna with great inertia of the mobile radar-the location control method as per the azimuth area is put forward in this paper. The control strate- gy is compared with the conventional control method. On the basis of the control system which takes the driver as the velocity inner loop, the hardware control circuit of the location loop controlled by the single chip microcomputer is given and the software imple- ment method for the location loop is described. With the actual control mode as basis, the improved location time as support and the simplified control strategy as main clue, The practical application of this new control method is described in detail.
