摘　　要：为解决全自动活塞式压力计在测量压力过程中测量时间长、系统稳定性差的问题,提出一种增广LQR的控制方式,利用增广LQR控制的快速响应、超调量小的特点实现快速压力检定、稳定系统。采用线性变化模型改进PSO算法(EPSO)去优化增广LQR控制器。利用MATLAB中的Simulink模块对所设计的控制系统进行仿真实验,验证设计控制系统的有效性。仿真结果表明,与常规PID、LQR控制器对比,使用EPSO优化增广LQR在对活塞式压力计进行控制时具有更强的鲁棒性和适用性。In order to solve the problems of long measuring time and poor system stability of automatic piston manometer in the process of pressure measurement,an augmented LQR control method to realize the rapid pressure verification and stability system using its characteristics of quick response and small overshoot was proposed.A linear change model was used to improve the PSO algorithm(EPSO)to optimize the augmented LQR controller.MATLAB and Simulink modules were used to conduct co-simulation experiments on the designed control system to verify the effectiveness of the designed control system.Simulation results show that compared with conventional PID and LQR controllers,the enhanced LQR optimized by EPSO has stronger robustness and applicability in the control of piston manometer.
