%X 为解决大深度快速上浮脱险压力曲线控制问题，设计了一种基于模糊自适应PID控制算法的模拟脱险试验装置气加压系统。对快速加压系统进行了理论分析，采用AMESim+Simulink联合仿真平台进行数字建模。分析了不同控制策略、气动调节阀延迟、阀芯特性和压力测量误差对加压系统控制效果的影响。运用模糊自适应PID控制策略提高了控制系统的动态响应速度、控制精度和鲁棒性，并保持系统的稳定性。计算机仿真试验和模拟脱险装置实物验证试验结果证实了该控制策略的可行性和有效性。<br>In order to solve the pressure curve controlling problem in deep buoyancy escape, this paper designs the escape simulation and experimental device of a gas pressurizing control system based on the fuzzy adaptive Proportion Integration Differentiation (PID) control algorithm. It analyzes the fast pressurizing control system in theory, and establishes its digital model with the AMESim + Simulink co-simulation platform. It then describes how the following factors-including control strategies, delay and spool characteristics of the pneumatic regulation valve, pressure measurement errors-influence the control effect of the pressurizing control system. It improves its dynamic responding speed, control precision and robustness of the gas pressurizing control system with the fuzzy adaptive PID control strategy, thus maintaining the system stability. The simulation results and the experimental results on the escape simulation device show that the fuzzy adaptive PID control strategy is feasible and valid
