本控制系统用于抑制大功率速调管输出微波功率宏脉冲平顶波纹，改善电子直线加速器输出束流的品质．控制方法采用微分线性逼近和矩阵算法对系统的输入和输出进行分析，求出代表系统响应的传输矩阵，从而将复杂的激励一响应计算转化为简单的代数运算．实验结果显示出宏脉冲平项波纹得到了有效抑制，说明采用自适应前馈控制来获得平坦的宏脉冲平顶是切实可行的．
The control system is used to suppress the high-power klystron output microwave power macro pulse flat top ripple, improve the electron linear accelerator output beam quality. The control method uses the differential linear approximation and the matrix algorithm to analyze the input and output of the system, and obtains the transmission matrix representing the system response, thus transforming the complicated incentive-response calculation into a simple algebraic operation. Experimental results show that the flat pulse of macro pulse is effectively suppressed, which shows that it is practicable to obtain flat macro pulse flat roof by adaptive feedforward control.
