The differential equation of a cruise control system is provided by the following equation:
Find the closed loop transfer function with respect to the reference velocity (vr) .
a. Find the poles of the closed loop transfer function for different values of K. How does the poles move as you change K?
b. Find the step response for different values of K and plot in MATLAB. What can you observe?
a box shaped barge 37m long, 6.4 m beam, floats at an even keel draught of 2.5 m in water density 1.025 kg/m3. If a mass is added and the vessel moves into water density 1000 kg/m3, determine the magnitude of this mass if the fore end and aft end draughts are 2.4m and 3.8m respectively.
a ship 125m long and 17.5m beam floats in seawater of 1.025 t/m3 at a draught of 8m. the waterplane coefficient is 0.83, block coefficient 0.759 and midship section area coefficient 0.98.
