ECG Mode Comparison Pole trajectory by changing ECG from 0.01 to 0.1 (Experimental Tests) By increasing ECG, Poles are getting closer to imaginary axis The smaller ECG, The more stable system
Pole trajectory by changing ECG from 0.01 to 0.1 (simulation Tests) By increasing ECG, Poles are getting closer to imaginary axis The simulation test results show the simulated system is more stable than real one but both have the same direction
PD Controller Mode Comparison Pole trajectory by changing Kd from 0.01 to 0.1 (Experimental Tests) By increasing Kd, Poles are getting further to imaginary axis The larger Kd, The more stable system
Pole trajectory by changing Kd from 0.01 to 0.1 (Simulation Tests) By increasing Kd, system is getting more stable The larger Kd, The more stable system
Changing ECG in PD Mode, Kd=0.05 Pole trajectory by changing ECG from 0.01 to 0.1 while Kd=0.05 (Experimental Tests) By increasing ECG, Poles are getting Closer to imaginary axis The smaller ECG, The more stable system
Pole trajectory by changing ECG from 0.01 to 0.1 while Kd=0.05 (Simulation Tests) By increasing ECG, Poles are getting Closer to imaginary axis The smaller ECG, The more stable system
Sampling Rate of Camera Pole trajectory by changing Sampling rate of camera from 2 to 30 frames per second (Experimental Tests) Changing sampling rate dose not have specific effect on pole trajectory
Pole trajectory by changing Sampling rate of camera from 2 to 30 frames per second (Simulation Tests) Changing sampling rate dose not have the same effect as experimental results
