The diameter of actual tangent circle is an important parameter for safety of boiler, the residual rotation is the key factor of flue gas temperature deviation at furnace exit.
实际切圆直径是锅炉稳定安全运行的一个重要参数，炉膛出口残余旋转是造成烟温偏差的主要原因。

Finally the parameter of the residual generator is optimized, so that the fault detection system is robust to the unknown inputs and simultaneously sensitive to the faults.
最后优化残差产生器的参数，使得故障检测系统对未知输入具有较强的鲁棒性，同时对故障具有较高的灵敏度。
