problem in designing a compensator for dc motor

[muoinhohn]

Hi all
I've a problem in designing a compensator for a dc motor.
In fact, the motor has the transfer function
motor:
0.01
------------------------------
0.005s^2 + 0.06 s + 0.1001

I want to use a lead or lag compensator to control the motor with dynamic response following:
1) Overshoot <= 5%
2) Settling time <= 1s
3) Steady-state error <= 1%

I tried many parameters for lag (and also lead) compensator based the method of response frequency design. But I don't find out correct parameters.
Anyone can help me to solve this problem, please.
Thank you very much.
Regards
Muoinho

may be... PID is good solution for this problem...I think...

You could try an Inverse-based controller design.
