MATLAB®’s Simulink® with Power PMAC Facilitates user-servo code generation for Power PMAC using Simulink®’s Embedded Coder (previously known as Real-Time Workshop). The objective is to fully automate code generation for Power PMAC’s servo loop closure routines (tasks) utilising Simulink’s® control blocks.
