In general digital control algorithms are multi-input multi-output (MIMO) recursive
digital filters, but there are particular numerical requirements in control system
processing for which standard processor devices are not well suited, in particular
arising in systems with high sample rates. There is therefore a clear need to
understand the numerical requirements properly, to identity optimised forms for
implementing control laws, and to translate these into efficient processor
architectures. By taking a considered view of the numerical and calculation
requirements of control algorithms, it is possible to consider special purpose
processors that provide well-targeted support of control laws.
This thesis describes a compact, high-speed, special-purpose processor which offers
a low-cost solution to implementing linear time invariant controllers. [Continues.
