before you bid must be experienced in the subjects mention below. if you are not please do not bother with bidding.
1- Understand the difference between open-loop and closed-loop (feedback) control systems and understand both the advantages and limitations of feedback control.
2- Understand the utility of the Laplace transform and transfer functions for modeling a variety of electrical, mechanical and electro-mechanical systems.
3- Understand the relationship of the poles (and zeros) of a system’s transfer function to its response, including classical time-domain transient performance specifications such as overshoot, rise-time, and settling-time.
4- Understand the relationship of a system’s poles to its stability; and stability analysis using the Routh-Hurwitz test, and the root-locus and the Nyquist plot
5- Understand the utility of the frequency-response of a system in both analysis and design; relate time-domain specifications to requirements on the frequency response, including the phase margin, gain crossover frequency etc.
6- Design lag, lead, lag-lead and P/PI/PID controllers using the root-locus and frequency-response (Bode plot) techniques
7- Understand the role of integral control in guaranteeing performance robustness in the face of uncertainties; problems associated with integral control, especially integrator windup; anti-windup schemes to mitigate the effects of actuator saturation
8- Use Matlab® as a computational tool to assist in the above objectives
