设计一个模糊控制系统控制一个加热炉的炉温，控制的目标是200℃，温度控制误差的范围是（-100℃，+100℃），误差的变化律是（-50℃/T，+50℃/T），T=10s，为控制周期。-A fuzzy control system design of a furnace furnace temperature control is the goal of 200 ℃, the range of temperature control error is (-100 ℃,+100 ℃), changes in the law of error is (-50 ℃/T,+50 ℃/T), T = 10s, the control cycle.
