In high-power fiber laser beam combining systems, the large beam-pointing errors, which are induced by limited precision of assembling, thermal deformation of mechanism and so on, will affect combining effects and bring serious damages to the systems. Beam-pointing experimental setup with two adaptive fiber-optic collimators is established, the large beam-pointing errors between combined beams are corrected using the stochastic parallel gradient descent control strategies based on variable power- in- the- bucket metrics and divergence metrics, respectively, and 200 W incoherent beam combining is achieved. This work is helpful for the high-power fiber laser beam combining in large pointing-error conditions.
