how to get the control signal from the pid controller?

suppose we have simple code like this

As=[matrix A]; Bs=[matrix B]'; Cs=[matrix A]; Ds = 0; Syss = ss(As,Bs,Cs,Ds); TF=tf(Syss); FE=1; C=pid(kp,ki,kd); T=feedback(C*TF,FE)

how can I get the control signal (output of the PID controller)?

sys=C/(1+C*TF);
step(sys)

I need to get the control signal which is the output of the PID. If I have system described above and I give the system step as reference signal step(T), how can I get the control signal vector.

That's exactly what I answered.
