2. The laser-guided missile shown in Figure 19 has a pitch moment of inertia of 90 kg m2. The control fins produce a moment about the pitch mass centre of 360 Nm per radian of fin angle Bin). The fin positional control system is described by the differential equation dB 0.2 + B() = u(1) where (1) is the control signal. Determine the differential equation relating the control signal (7) and the pitch angle (1). ((1) Fig. 19 Laser-guided missile 40
