When using MATLAB to compute it, the result obtained is K*M - (K*M)/exp(t/tao). Why is the sign of the exponent different between the two? I hope those who understand can explain this to me; I’m just starting to learn control systems.
exp(-x) = 1/exp(x), right?
What does the original poster mean? I don’t understand; I’m just starting to learn *control
