The differentiation provides signals that are zero in steady-state conditions. This means that the downstream gains of the differentiation can be scheduled with respect to AOA/AOS without creating unwanted feedback loops. The integration provides smoothing which allows gains scheduled upstream of the integration to include noisy signals. Easy bumpless switching is provided between store groups. The proportional loops have no steady-state influence. DPIA controllers can easily avoid integral windup as the surface and rate limits limit the integrator.
