EXPERIMENT2STEP RESPONSE ANALYSIS OF A SYSTEM USING MATLABAND SIMULINKAIM:Electric traction motors are utilized on trains and transit vehicles. The detail block diagram model with transfer function of the power amplifier, armature control motor, and sensor is shown in the figure.Compute the closed loop transfer function and investigate the step response of w to wd.ALGORITHM:MATLAB CODE:clear all;close all;N1!1"#;$1!1 1#;%1tf&N1,$1'N(!1#;$(!( ".)#;%(tf&N(,$('*1".1;T+1%1,%(-feedback&T+1,*1'%.)/";T+(-,%.0feedback&T+(,1'subplot&.,1,1'step&0';1for omegan2..) and zeta"."1211for wn2..)11for zeta"1 3N$045E$N341!)/""#;$EN1!( " )/"(#;651tf&N341 ,$EN1'subplot&.,1,('step&651';title&73N$045E$7'1for zeta".2"2 3N$E8$045E$N34(!)/""#;$EN(!( 1"..9( )/"(#;65(tf&N34(,$EN('subplot&.,(,1'step&65(';title&73N$E8$045E$7'1for zeta1 C8:T:C0;;< $045E$ N34.!)/""#;$EN.!( 1/=.9> )/"(#;65.tf&N34.,$EN.'subplot&.,(,('step&65.';title&7C8:T:C0;;< $045E$7'1for zeta( 6?E8$045E$N34/!)/""#;$EN/!( (9/ )/"(#;65/tf&N34/,$EN/'subplot&.,1,.'step&65/';title&76?E8$045E$7' SIMULINK MODEL:@TE5 8E@56N@E 6+ T*E 0-6?E @
