【摘要】 该文对电厂锅炉燃烧送引风控制系统进行了讨论,对该系统从多变量角度进行了分析,引入总和时间常数法对解耦后的等效对象进行了校正、整定和计算机仿真,给出了仿真曲线。结果表明,总和时间常数法整定系统简便易行,控制质量好,能够满足工程要求,有推广价值。更多还原

【Abstract】 This paper discusses boiler forced draft and induced draft control system and analyses the system by multivariable control theory, decoupled equivalent controlled objects are tuned and adjusted by sum time constant approach, the control system is simulated by computer, step response curves are given.Result shows that the approach is simple and convenient, there is a good quality in the control system. The approach can meet the engineering,requirements and is worth spreading.更多还原
