Pipelining digital feedback controllers

72 p.Most modern dynamical systems and filters in digital signal processing, telecommunications and control are implemented by digital electronics in terms of VLSI circuits. Pipelining processing can either increase the sampling speed or reduce the power consumption in VLSI implementation. While FIR digital filters can be pipelined at arbitrary levels by inserting latches, IIR digital filters are to be reformulated into a look-ahead filter form in the pipelining processing. For stability and convergence of the look-ahead filter, it is essential that the designed polynomial be stable. While many digital feedback controllers are unstable systems, there are no time-invariant approaches to design stable look-ahead systems for unstable IIR filters.Master of Science (Computer Control and Automation
