摘　　要：水泥产业属于高耗能的企业,而余热发电是水泥厂节能降耗和减少污染物排放的重要手段。为在余热发电系统高扰动的工作环境中仍保持电能的稳定,提出了建立指数型终端滑模变结构的励磁和汽门开度综合控制器;然后用MATLAB软件构建模型,并在三相短路和三相断路故障条件下分别进行仿真,与采用自适应终端滑模变结构控制的仿真结果进行对比分析,结果表明采用指数型终端滑模变结构控制方法使被控对象具有更好的动、稳态特性,提高了电能的稳定性。Cement industry is an energy intensive businesses,and using waste heat power generation is an important means of energy saving and reducing emissions in cement plants. In this paper,in order to keep the power stability of the high disturbance environment in waste heat power generation system,we established the excitation and valve opening integrated controller based on exponential terminal sliding mode variable structure. And then,we built the model based on MATLAB,and under the condition of the three phase short circuit and three-phase circuit breaker fault,we performed the simulation experiment. The result shows that using the exponential terminal sliding mode variable structure control system,the controlled object has better dynamic and steady state characteristics,which improves the stability of electrical power,compared with the adaptive terminal sliding mode variable structure simulation result.
