摘　　要：分析了温度传感器的时间常数对2α控制的影响,由于时间常数并不确定且超前环节会放大噪声,对温度传感器的直接修正不能得到可靠的α2给定.在发动机稳态和过渡态分别采用n2r25和n2r给定的2α控制方式,用加权的方法在两种控制方式间进行选择.根据实际试车中n2r信号的变化获取加权系数,从而完成发动机在各种状态下的2α控制.通过试车验证了方法的可行性.The influence of time constant on α2 control was studied,and reliable α2 reference can not be acquired for uncertain time constant of temperature sensor and amplifying noise for lead link.The control method of α2 in steady and dynamic was given separately according to n2r and n2r25,and the weighted approach was used for selection of the two control methods.The weighted coefficient for these two methods was obtained from variation of n2r in engine test,and the control of α2 could satisfy the requirements of all conditions.The control method was validated on test-bed.
