An offset between the value of the controlled variable and its set-point remains
We observe that by increasing (in absolute value) 𝐾𝑐, the final steady state value of ℎ′(𝑡)decreases, i.e. it gets closer to the set-point of 0. Correspondingly the error 𝜀decreases (in absolute value). However, an offset between the value of the controlled variable and its set-point remains. This is as expected for a P controller. Note […]
