The invention discloses a rotation speed fuzzy control chemical mechanical system. A main control station is provided with a fuzzy control device and a processor. The fuzzy control device comprises adifferentiator, a derivator, a fuzzification interface, an output conversion module, an inference engine and a knowledge base, a rotation speed sensor provides a rotation speed measured by the rotation speed sensor to the differentiator, the differentiator calculates an error value E through subtraction of a set rotation speed input by an operator from the measured rotation speed, the derivator calculates an error change rate dE/dt through the derivator through the error value E, the error value E and the error change rate dE/dt are provided for the fuzzification interface, and the error valueE and the error change rate dE/dt are subjected to fuzzification assignment. 种转速模糊控制的化工机械系统，主控工作站具有模糊控制装置和处理器，模糊控制装置包括差分器、微分器、模糊化接口、输出量转换模块、推理机、知识库，转速传感器将测得的立式电机的转速提供给差分器，差分器将操作人员输入的设定转速与测量转速相减得到误差值E，误差值E经过微分器得到误差变化率dE/dt，误差值
