Manuscript received June 3 2015 revised August 18 2015 J A et al 1 showed International Journal of Electrical Energy Vol 3 No 3 September 2015. The companys extensive offering includes turnkey electrical automation instrumentation and control systems supported by a comprehensive service portfolio to optimize performance reliability and efficiency while minimizing environmental impact brPage It is known as Nyquist stability criterion It is based on the complex analysis result known as Cauchys principle of ar gument Note that the system transfer function is complex function By applying Cauchys principle of ar gument to the openloop syste and Control I. We are learning how to analyze mechanisms. but what we’d like to do is make them do our bidding. We want to be able to control them —. to make a robot trace a particular path, say. Part 2.

The reason is that the performance of most control systems is judged based on the time due to certain test signals. . Frequency response concepts and techniques play an important role in control system design and analysis. . Closed-Loop Behavior. In general, a feedback control system should satisfy the following design objectives:. frequency-response studies.
