Abstract:

The report contains the results of research into techniques for converting analog controllers filters to digital controllers, such that the characteristics of the control system remain essentially the same. A major consideration was to employ as low a sampling rate as possible in the digital controller. The control system considered throughout the report was the Pershing Weapons Systems roll-axis control system. First a technique developed by B. C. Kuo was considered. This technique yields excellent results at high sampling rates, with the results not as good as the sampling rate is decreased. Next various numerical integration techniques were investigated. Only the trapezoidal rule yielded good results at low sampling rates. Finally, various techniques developed for the design of digital filters were considered, with only the bilinear transform giving good results at low sampling rates. However, the bilinear transform is equivalent to the trapezoidal rule of numerical integration. Author
