Abstract: Under investigation in this paper is KP equation. Bilinear equation is obtained via the dependent variable transformation. the rogue waves with a controllable center are reported for KP equation by using symbolic computation software maple18, Which contain two free parameter α and β.By choosing different parameters α and β can control the center of the rogue waves, The dynamic properties of the rogue waves are three dimensional plots sand density plots.

Key words: KP equation, rogue wave, bilinear equation
