水面舰艇集体防护系统PID控制分析

摘要

The collective protection system is an essential part of surface ship defense. In order to achieve the precise and quantitative control of the system pressure,a full mathematical model is formed based on the system pressure control equation and by adjusting the mechanism equation. The mathematical model is linearized by incremental equations for further transfer function analysis. PID parameters are test⁃ed and confirmed to realize stability and optimized control. The model is then formed with the PID parame⁃ters to test its performance under variable working conditions. The simulation results show that the system pressure successfully reach the desired value,while various flow rates and system volumes can also be sat⁃isfied. In particular,the control limitation of the valve must be concerned in this model,as the target value of pressure may not be reached if the flow rate is too high. Overall,the simulation research builds solid fun⁃damentals for future engineering applications of large space collective protection systems.%集体防护系统是水面舰艇防护的重要组成部分。为实现集体防护系统精确的定量控制，基于集体防护区域压力控制方程以及调节机构（超压控制阀）方程，构建系统增量方程线性化传递函数，通过传递函数确定PID参数以实现系统稳定及优化控制。构建系统整体数学模型，结合PID控制模块研究系统变工况特性。模拟结果表明：系统具有良好的超压设定值实现能力及动态特性，能够满足较大的进风量及舱容变化。系统数学模型必须考虑超压控制阀的调节能力限制，过大的送风量可能导致系统无法实现设定的超压值。建立并分析集体防护系统数学模型，为系统向大空间区域工程应用奠定良好的理论基础。
