Unformatted text preview: ω gc . (c) Closedloop Bode plots and the actual bandwidth frequency. How does it compare with your estimated range in part (b)? (d) The closedloop system time constant and the 2% settling time. Then, simulate the unit step response and check your predictions. (e) Is the closedloop system 1 st or 2 nd order dominant? Please explain. PROBLEM 3 : FPE, Prob. 6.39, p. 401. Given : Steering dynamics of a ship: where v is the ship’s lateral velocity in meters per second and δ r is the rudder angle in radians. Find : (a) for K = 0.2 using the MATLAB bode command. (b) Gain crossover frequency and PM, phase crossover frequency and GM on the Bode plot. (c) Is the ship steering system stable with K = 0.2? (d) Value of K for PM = 30º and the corresponding gain crossover frequency....
