| 摘要: |
| 闪变仪在每次使用前应进行自校验，以保证仪器的准确性。自校验实际上是对仪器的某些参数进行校准。闪变仪校准时需要调整的参数是传递函数的放大倍数，即增益K。提出利用比例、积分(PI)控制算法确定K值。在计算中适当选取PI控制参数Ki，Kp的值，使得收敛速度与采样频率无关，计算结果表明了算法的有效性。 |

| Abstract: |
| To ensure the veracity,self-checkout must be done every time before flickermeter is used. Self-checkout is actually to adjust some parameter of flickermeter. The parameter must be adjusted is the gain K in the transfer function. A method is proposed to determine K using PI control arithmetic in this paper. The calculated results show the effectiveness of the method by means of choosing proper Ki and Kp values of the PI control parameter and making convergence speed independent of sampling frequent. |
