I want to implement flux weakening control for PMSM, but getting very odd results. so anybody here who has implemented Field weakening control can help me?

Hello folks, I want to implement Flux/Field weakening control for Permanent magnet synchronous motor (PMSM). I referred some papers and tried to implement the fundamental Field weakening control but the results are not satisfactory. When I increase the speed of the motor so the torque reduces and correspondingly the q-axis current also reduces but the d-axis current remain constant which should also change accordingly. so if you guys have implemented the basic FW control so please help me. thanks.
