# Consider the electromechanical dynamic system shown in Figure 1 It consists of a cart of mass m moving without slipping on a linear ground track

Consider the electromechanical dynamic system shown in Figure 1(a). It consists of a cart of mass m moving without slipping on a linear ground track. The cart is equipped with an armature-controlled DC motor, which is coupled to a rack and pinion mechanism to convert the rotational motion to translation and to create the driving force for the system. Figure 1(b) shows the simplified equivalent electric circuit and the mechanical model of the DC motor, where r is the radius of the motor gear (which in this case is also a wheel of the cart). Ra is the resistance of the armature circuit. The torque and the back emf constants of the motor are K, and Kb, respectively. Neglect the armature inductance and the mass moment of inertia of the motor. The driving force fis related to the torque by f -Tm/r. Tm is the torque generated by the motor.
