为了无调整地进行高性能的温度控制,相对于PID调节器只按照反馈方法的控制,进行了根据反馈和前馈复合的算法控制管式电炉的试验。 这种计算法,采用布置在炉心、加热器及其周围的多个传感器传递来的温度信息,用微型计算机进行控制,并且包含着也能适合于其它形式、用途、规模的炉子的控制技术。 已证明,该系统与PID调节器控制相比,控制装置不需要调整,控制精度高,应答速度快,经济性能优越。 In order to carry out high-performance temperature control without adjustment, the experiment of controlling the tubular electric furnace based on the algorithm of feedback and feed-forward is carried out only in accordance with the feedback control of the PID regulator. This method of calculation uses the temperature information transmitted by the plurality of sensors disposed in the core, the heater and its surroundings, is controlled by a microcomputer, and includes a control technique of the furnace that is also adaptable to other forms, uses, and scales. It has been proved that compared with the control of PID regulator, the system does not need to be adjusted, the control precision is high, the response speed is fast, and the economic performance is superior.
