The boundary control problem for the hyperbolic equation is considered for the case, when the angular coefficients of characteristics have the same sign. The control functions are constructed in an explicit form. The conditions of controllability are found for different periods of control.
Keywords: hyperbolic equation, boundary control, Cauchy problem.
