基于数字PID控制的鱼雷深度模拟系统研究

为了提高鱼雷半实物仿真试验中深度模拟设备的响应速度和控制精度等性能指标,开发了一种基于PC104产品的动态数字比例-积分-微分（PID）控制系统。该系统在结构上采用上、下位机的模式,利用串口进行通信;在控制算法上,针对PID控制存在的积分饱和、抗干扰和动态过程加速等问题,设计了相应的控制修正算法,确保了系统的控制速度和精度。通过对鱼雷半实物仿真试验数据分析可知,所得到性能指标满足实际要求。

A Digital PID Control System for Torpedo Depth Simulator

For improving such performances as response speed and control precision of a depth simulator in torpedo hardware-in-the-loop simulation test, a dynamic digital proportion-integration-differentiation（PID） control system was developed on the basis of PC104 products. The control system adopts the master/slave computers structure, and realizes communication through a serial port. Aiming at the problems in PID control, such as integral saturation, anti-interference, and dynamic process acceleration, a corresponding control correction algorithm was designed to guarantee the control speed and precision of the system. By analyzing the hardware-in-the-loop simulation test data of a torpedo, it is proved that the depth simulator with this PID control system achieves very good performances and meets the requirement in actual use.
