确定性系统中建立一个跟踪系统让稳态误差变成0

- This scr ipt demonstrates designing a tracking system with feedback and

　 gain compensation to bring steady-state error to 0 and a settling time

　 of 2.5 seconds.　The response to a unit step is simulated and plotted

　 to compare the system before and after compensation.　This uses the

　 STEP function from the system id toolbox and also ODE45 function to

　 compute the step response.
