某舰空导弹非线性控制系统数字化改进设计

Digitized Design on Nonlinear Control System of Some Ship-Air Missile

在不改变原硬件组成的条件下,对某舰空导弹模拟控制系统的数字化改进进行了研究。用模拟化设计将连续控制系统转为离散控制系统,给出了数字俯仰回路,以及非线性自动驾驶仪软硬件组成。数字仿真结果表明:设计的数字控制系统性能与模拟系统基本一致。

The digitalization improve design of the analogue control system in some ship-air missile while the original hardware was not changed was studied in this paper. The continuous control system was changed to the distrete control system by the analogue design method. The pitch channel and the hardware and software of the digital nonlinear autopilot were given out. The numerical simulation results showed that the performance of the digital control system designed was similar with the analogue control system.
