This paper presents the dynamic model of multibody systems driven by electric motors, the so-called electromechanical systems. The mechanical systems considered in this study include an open loop and/or a closed loop, a full-actuated and an underactuated one. The dynamic model of this electromechanical systems is established in matrix form by applying the Lagrangian equation with and without multipliers and substructure method.

In this paper, the target-tracking problem of a 3-axis camera gimbal mounted on a flying vehicle is considered. In order to keep the camera’s line of sight continuously pointing to a moving target, an optimal controller using LQR control techniques is applied. The motion equations of the gimbal system are derived by the Lagrangian approach considering the vehicle motion.

In the present paper, a form of equations of motion for the Chaplyghin's systems is introduced. The scheme for writing these equations is very simple, because they are established by means of only the matrix of inertia of Lagrangian function and are written in the matrix form.

In Section 1.5 of the textbook, Zak introduces the Lagrangian L = K − U , which is the difference between the kinetic and potential energy of the system. He then proceeds to obtain the Lagrange equations of motion in Cartesian coordinates for a point mass subject to conservative forces, namely, d dt ∂L ∂ xi ˙ − ∂L = 0 i = 1, 2, 3. ∂xi (1)

Vector and matrix concepts have proved indispensable in the development of the subject of dynamics. The formulation of the equations of motion using the Newtonian or Lagrangian approach leads to a set of second-order simultaneous differential equations. For convenience, these equations are often expressed in vector and matrix forms. Vector and matrix identities can be utilized to provide much less cumbersome proofs of many of the kinematic and dynamic relationships. In this chapter, the mathematical tools required to understand the development presented in this book are discussed briefly.
