PI based controller for 3 leg and 4 leg inverter

PI-based dq0 CONTROLLER DESIGN FOR FOUR LEG INVERTER WITH LC FILTER is required. And also the three-phase three-leg controller is required. The controllers should have both an inner current and an outer voltage loop. You should give me the option to select cross-over frequency. Freshers are welcome. I can give you the papers IF YOU WANT. I need complete the controller design in 2 days. The price is negotiable.
