Abstract: In order to auto control temperature and humidity of the earthworm biological treatment of municipal sludge treatment reactor. By using of SVM (support vector machine) and MPC (model predictive control) technology, an automatic control model was constructed. The temperature and relative humidity of the earthworm biological reactor could be controlled accurately according to the set point. The method can be used to control the temperature and relative humidity of the reactor.

Key words: earthworms bioreactor, support vector regression, model predictive control

摘要： 为实现自动控制蚯蚓生物处理反应器处理城市污泥过程中温度和相对湿度， 采用SVM(support vector machine)技术结合MPC(model predictive control)模型控制技术建立自动控制模型，准确调节蚯蚓反应器内强耦合的温度和相对湿度，在预定时间有效地控制实际温度和相对湿度达到预设目标。
