“…Lions examined the problems in detail when the control function is at the right hand side and in the boundary condition of the hyperbolic problem. Furthermore, when the control is in the boundaries [2][3][4], in the coefficient [5][6], and at the right hand side of the equation [7,8], there have been some control problem studies for different types of cost functional. As for the control of initial conditions, Lions mentioned the control of the initial velocity of the system in detail but stated briefly the control of initial status of the system solving the .…”
