A method to solve active optics corrective force is introduced  which is based on Householder transform of Zernike polynomial wave front fitting  this method is different from the traditional least square method and Gram-Schmid orthogonal method  because it does not bring ill-conditioned polynomial without constructing normal equation  so it can avoid calculation error  wave front fitting is precision. Based on the coefficient of the Zernike polynomial and the response function of the each actuator  the stiffness matrix of the primary mirror is built  and then adopting the damp least square method to calculate corrective force. Based on this method  cp400m test mirror is simulated many times  the calculation result approve: if the Householder transform is adopted  wave front fitting is precision  the result is stabilization and corrective effectiveness is better.
