OPTIMIZATION OF HIGH-TEMPERATURE AND HIGH-PRESSURE TRIAXIAL TESTING MACHINE CONTROL SYSTEM BASED ON PARTICLE SWARM ALGORITHM

Optimization of High-temperature and High-pressure Triaxial Testing Machine Control System Based on Particle Swarm Algorithm

By combining particle swarm algorithm (PSO) with conventional PID, the hydraulic and temperature control systems of high-temperature and high-pressure triaxial testing machine was analyzed and studied, the mathematical models of hydraulic system and temperature control system were established.The performance of the control system under conventional
