On Problems of Boundary Control of String Vibrations with Conditions on the State Functions at Given Intermediate Time Moments

For the string vibration equation with given initial and final conditions, we consider six boundary control problems with given different intermediate conditions on the values of the deflection function and the velocities of the string points. We propose a constructive approach for constructing the boundary control of string vibrations according to a single scheme for all problems. A comparative analysis of the results was carried out.
