Analytical expressions of control actions are obtained for a fourth-order linearized model of the flying vehicle longitudinal motion. Synthesis is based on original decomposition of the control object as well as on the previously elaborated method of modal control by MIMO-system. The method does not require solving special matrix equations (such as Silvester equation), takes the same form for continuous and discrete cases of the system model assignment, has no restrictions on algebraic and geometric multiplicity of the assigned poles, is easily realized in the MATLAB environment. Numerical simulation results are given to control the aircraft longitudinal motion by applying analytically synthesized control laws represented by the graphs of transient processes and controlling actions.
