PID control
Thread Content
Hey experts, how did you solve this problem? I need the specific calculation steps. Thank you! The initial output U0 of a certain controller is 1.5 VDC; when a 0.1 V step input is applied to UI (with the set value remaining unchanged), U0 becomes 2 V. Subsequently, U0 rises linearly; after 5 seconds, U0 is 4.5 V. What are the proportional gain, proportional bandwidth, integration time, and differentiation time respectively?
△Uo= 2-1.5=0.5V； △Ui=0.1V, K=△Uo/△Ui=0.5/0.1=5. Sensitivity=1/K*100%=20%. (2.5-2)=【(4.5-2)/(5-0)】*(Ti-0); Ti=1 min, Td=0
Thank you so much; I still don’t quite understand PID
May I ask how the 2.5 in 2.5-2 comes about? Thank you
Amazing, truly incredible; I’ve wasted my time studying automatic control principles
