The Shanghai Synchrotron Radiation Facility (SSRF) Phase II beamline project (SSRF Phase II) will implement the new lattice with dual-canted insertion devices, superbends and superconducting wiggler. The emittance coupling is one of the most important parameters for the high brightness storage ring light sources. It is often less than 1% in the third-generation storage ring light sources. In this paper, the sensitivity of emittance coupling to magnetic alignment errors in the SSRF Phase II is presented. Sixty skew quadrupole magnets are utilized to correct the emittance coupling with gradient descent algorithm. The emittance coupling obtained in the SSRF Phase II lattice is below 0.3%.
