Abstract :
The paper presents a method for digital PID and first order controller synthesis based on frequency domain data alone. The techniques given here first determines all stabilizing controllers in respective three parameter spaces from measurement data. In both PID and first order controller cases, the only information required are frequency domain data (Nyquist-Bode data) and the number of open-loop RHP poles. Specifically no identification of the plant model is required. Examples are given for illustration
