hi. I am having a problem with the state variable controller.I am tryn
to locate closed poles in the left hand plane such that my output graph
has no overshoot.I am modeling a spring and dashpot system.It has two
masses.m1 and m2.My output of interset is the diplacement of m1(is the
bottom mass) calle x.I have modelled the system in simulink and it is
workn,but i am having difficulty in the controller part.I have designed
the controller but i am getting overshoot on my output graph(x) which i
dont want.I have choose poles (-2 -2 -4 -4) and it is stil not
working.The follwing are my two state differential equations

m1 x = k (y – x) + b (y – x) – (m1 + ∆ m) y . . . . SDE1

m2 y = F – k(y-x) – B ( y –x) – m2y. . . . .SDE 2

I chose B = 1,K =1. m2 =1. m1 =1. These equations i have modelled in simulink.please help with the state variable controller part.Thanx in advance

m1 x = k (y – x) + b (y – x) – (m1 + ∆ m) y . . . . SDE1
