Advantage of low complexity in digital controllers with finite wordlength
The paper shows the main advantage of certain low-complexity digital control strategies over techniques resulting in more complex control systems; that is, the superior level of performance when subjected to finite wordlength effects. Examples demonstrate the performance limitations associated with highly complex control laws and the benefits of using properly selected, simple control schemes when implemented with fixed- and floating-point arithmetic and restricted number of bits.
