EET309: Tutorial 5 1. Determine the dc gain, undamped natural frequency, damping ratio and damped natural frequency for the following transfer function. (a) 10 2 25 ) ( 2 + + = s s s G (b) ) 8 )( 5 ( ) 3 ( 2 ) ( + + + = s s s s G (c) ) 3 1 )( 3 1 ( 4 ) ( j s j s s s G - + + + - = (d) A unit feedback system with an open loop transfer function of ) 4 ( ) 1 ( 7 ) ( + + = s s s s G o 2. From block diagram below, tell where the closed-loop poles are located: (a) (b) ( 29 2 3 4 4 8 2 3 4 5 - + - + - + = s s s s s s s T (c) ( 29 2 2 2 2 1 2 3 4 5 6 7 - - - - + + + = s s s s s s s s T 3. An RLC circuit has differential equation relationship as follow v i dt di dt i d 9 16 5 23 2 2 = + + Where i is the output current and v is the applied voltage. Both variables change with time t . (i) Obtain its transfer function. (ii) Determine the dc gain, the undamped and damped natural frequencies and its damping ratio. (iii)
