Carry out a system design procedure using observer design methodThe tasks for the Term Paper (Control systems).
1. Obtain the system transfer functions: - for control input signal (x/Td=0); - for disturbance input signal (Td/x=0); using block diagram transformation theorems;
2. Obtain the system transfer functions: using the Mason’s gain rule and compare the obtained results with the results in item.1; - for control input signal (x/Td=0); - for disturbance input signal (Td/x=0);
3. Obtain your system’s state-space models: - for control input signal (x/Td=0); - for disturbance input signal (Td/x=0);
4. Compare the characteristics (step response, impulse response, Nyquist diagram, Bode diagram, Nichols diagram, Gain and Phase Margins, Pole/Zero Map) of your control system equivalent transfer functions for control input signal (x/Td=0) and disturbance input signal (Td/x=0) (obtained by the usage of block diagram transformation theorems and the Mason’s gain rule) using the possibilities of linear analysis.
