| 针对惯性仪表的复合校准问题，设计了基于离心-温度复合装置的自学习切换控制方法，实现了高精度、高均匀性的温度场控制。根据离心机不同工况下的温度箱控制系统结构不同，切换控制方案可满足系统在高低温下的精度要求，自学习PID控制算法解决了控制过程中存在的温度波动问题。离心机旋转状态下和非旋转状态下的实验结果表明：该控制系统性能良好，在-55～80 ℃内的温度控制误差在±0.1 ℃之内。 |

| Aiming at the problem of compound calibration of inertial instruments, a self?learning switching control method based on a centrifugal?temperature compound device is designed to realize the temperature control with high precision and high uniformity. According to the different structure of the temperature box control system under different working conditions of the centrifuge, a switching control scheme is designed to satisfy the accuracy requirements at both high and low temperature conditions. A self?learning PID control algorithm is designed to solve the temperature fluctuation problem in the control process. The experimental verification is carried out under the rotating state and static state of the centrifuge respectively. The results show that the control system has good performance, and the temperature control accuracy is better than 0.1 ℃ in the temperature range from -55～80 ℃. |
