强瞬变热环境下高温结构快速变温跟踪控制试验方法及验证

To simulate the intense transient thermal environment of advanced aero-engine in laboratory，an experimental system was constructed to achieve rapid temperature tracking control. Two control methodologies tailored to different temperature variation rates， i.e. single-loop double-acting proportion integration differentiation (PID) control method based on Arduino and double-loop multisegment PID control method based on Eurotherm， were experimentally investigated and compared. Parameters tuning was validated using Simulink simulations，and the experimental system was utilized to conduct rapid temperature tracking tests. Within the temperature range of 300 ℃ to 650 ℃， both controllers achieved control errors below 6.83% when tracking triangular and trapezoidal wave targets. The Eurotherm-based controller exhibited clear advantages，achieving a maximum temperature change rate of 100 ℃/s.
