Control Systems (Unity Feedback Loop; Nyquist Contour; Routh-Hurwitz Analysis)
A process has a transfer function: {see attached} and is included in a unity feedback loop with a proportional controller Kp in a feedforward branch of the control loop. (a) Sketch a Nyquist contour for this system (b) Apply the Nyquist stability criterion to find a suitable range of K for stable closed loop system behaviour. ...continues
Bode Plot; Root Locus; Nyquist
(a) By drawing a Bode plot (with reasonable accuracy at frequencies of interest) and then using a rough sketch of the (full) Nyquist diagram, assess the stability of the following system in a unity gain, negative feedback configuation {see attached} (b)What would your conclusion in (Q4a) have been if the feedback loop had pos ...continues
Consider a unity negative feedback system with {see attached} (a) Sketch the open loop Nyquist diagram {see attached} using rough Bode magnitude and phase plots with reasonable accuracy for {see attached}. Show the diagram for {see attached} (using symmetry) with a dotted line. (b)Use the Nyquist diagram in question (a) to ...continues

Nyquist; Bode Plot; Root Locus
a) Analyse the closed loop stability of the system with open loop transfer function {see attachment} i)Make a sketch of the Bode diagram and hence the full Nyquist diagram, showing all relavent details ii) If the system is unstable, state the number of closed loop right hand plane poles and comment on how you might stabili ...continues
Consider a block diagram describing a system under proportional-integral control (as show in figure in attachment): Find the contraints and determine the range (using the Routh-Herwitz criterion) of Kp and Ki. Also, find the closed loop system transfer function assuming the controller gains are set to a specific value. *(Ple ...continues
