Selection of DSP/MCU

Greetings Community members!!!,

I've got a project to design a variable power supply(major specs below) which can drive a triangular current of ~40A (DC to 15Hz) through a RL load of 0.8Ω+40mH with available source of 3-phase 415V.

I made a basic scheme as attached, As I'm new to this arena I'm unable identify suitable DSP or MCU unit for my project.

Can anyone help me out in selecting the suitable DSP/MCU and reference designs???

Major Specs:

Output Voltage:90V

Output Current:40A

Input Voltage: 3-Ph, 415V, 50Hz,

Regulation: 1%,

Control: 0-10V signal(preferred), or RS232 or any other
