Abstract: In order to improve the precision and response speed of the 1000-hour static pressure test of FRP pipe, and to realize the real-time tracking of the target, a model reference adaptive control strategy based on generalized-error was proposed. Firstly, the mathematical model of static pressure detection system was established. Secondly, according to the Lyapunov stability theory, a model reference adaptive controller based on generalized-error was designed. Then，the Simulink simulation model was established, and the validity of the method was verified by comparing the adaptive control and PID control. Finally, the detection system platform was built, and the control effect was further validated by 1000 hours static pressure test. The results showed that under the adaptive control strategy, the actual pressure value of the detection system can follow the expected pressure value well, and the steady-state error does not exceed ± 0.03 MPa, which fully meets the static pressure detection accuracy requirements of FRP pipe.

摘要： 为提高玻璃钢管道的1 000 h静压检测试验的精度和响应速度，实现对目标的实时跟踪，提出了一种基于广义误差的模型参考自适应控制策略。首先建立了静压检测系统的数学模型，其次根据李雅普诺夫稳定性理论，设计了基于广义误差的模型参考自适应控制器，然后建立Simulink仿真模型，通过自适应控制和PID控制比较验证了该方法的有效性，最后搭建检测系统平台，通过现场1 000 h的静压检测试验对控制效果进一步验证。结果表明，在自适应控制策略下，检测系统的实际压力值可以较好地跟随期望压力值，稳态误差不超过±0.03 MPa，完全满足玻璃钢管道的静压检测精度要求。
