Active Filter PI Current Control Simulink

Hello folks, I'm simulating a shunt active filter with PI current control. Basically looks like a simple schematic but having lot of troubles. I can't generate the switching signals to control the inverter (the error is compared with the triangular carrier) and the filter current never tracks the reference. File attached. Hope I can find an answer. Thanks people.
