Underdamping problem on Simscape and Simulink for large value of Kp #13

Closed badmo05 closed 1 year ago

badmo05 commented 1 year ago

when I input the values of kP from the experiment (8.463) on either Simulink or Simscape, the graph shows an unstable system. I followed every step as described. It only works for small gain between 1 & 4.

Please double check you have set the correct parameters.

badmo05 commented 1 year ago

I do have the correct parameters, the same as lab 3. The problem arise only for Kp>5

AreteQin commented 1 year ago

Here are the reference values of the parameters: L = 1.49e-3; R = 2.04; Kt = 260/(10002*pi); Kb = 1.94e-2; B = 1.9e-4; J = 2.8e-6;

my simulation is exhibiting the same behaviour, also for values of kp > 5. Parameters match those listed above, tho I dont think Kt fits anywhere?

Sorry, there is sth wrong with GitHub. kt should be image
