Please feel free to share your knowledge about intuitive examples for offset function in optimal cost functional. I've illustrated one of the case examples, attached here.
PID controller is reportedly widely built and used in control systems engineering for industrial applications. The PID-controller has a transfer function as: (Kd*s^2+Kp*s+Ki)/s. Therefore, it...

It seems the state evolution ode; xdot=f(x,u), is known to satisfy f(0,0)=0, hence f(0,u(0))=0, then can we conclude at any control system, always u(0)=u(x=0)=0, and get the result that...
