摘要
针对蒸汽茶叶杀青机在运行过程中难以稳定维持预设温湿度的问题,提出一种基于微波扰动与模糊PID协同控制的温湿度调控方法。该方法通过将微波扰动技术应用于湿度控制,同时采用模糊PID算法实现温度精确调节,这种改进方法有效解决了传统控制方式中温湿度参数相互干扰的技术难题。在杀青温度为95℃、湿度为95%、时间为1 min时,温湿度虽然存在轻微波动,但始终保持在较小的可控范围内。结果表明,结合微波扰动和模糊PID的温湿度控制方法能够有效确保蒸汽茶叶杀青机内部环境的稳定性,使茶叶处于最佳杀青状态。这种精确的温湿度控制方法不仅大幅提高了杀青工艺的一致性和重复性,而且提升了成品茶叶的品质,为茶叶优良风味特征和营养价值的形成提供了可靠保障。
To address the difficulty of stably maintaining preset temperature and humidity during the operation of the steam tea fixing machine,a temperature and humidity regulation method based on the coordinated control of microwave perturbation and fuzzy PID was proposed.This method applied microwave perturbation technology to humidity control and employed the fuzzy PID algorithm for precise temperature regulation,effectively solving the technical challenge of mutual interference between temperature and humidity parameters in traditional control methods.When the fixing temperature was 95℃,the humidity was 95%,and the time was 1 min,although slight fluctuations existed in the temperature and humidity,they were consistently maintained within a small controllable range.The results showed that the temperature and humidity control method combining microwave perturbation and fuzzy PID could effectively ensure the stability of the internal environment of the steam tea fixing machine,keeping the tea leaves in the optimal fixing state.This precise temperature and humidity control method not only significantly improved the consistency and repeatability of the fixing process but also enhanced the quality of the finished tea products,providing reliable assurance for the formation of excellent flavor characteristics and nutritional value of tea.
