One of the key issues in implementing this type of controller is how to handle the clamping function. Think about how to wrap a finite state machine controller around the main PI; to enable the integrator after the clamp has cleared in an appropriate manner. This topic is in addition to how to handle the bit growth of the accumulator; which is an issue in any FIR or IIR filter design. -James
