For all problems -given a transfer function G(s) sketch the magnitude and phase characteristics in the logarithmic scale (i.e. Bode-plots) of the system using the following rules-of-thumb: i. "Normalize" the G(s) by extracting poles/zeros, substituting s-jw and writing the TF using DC-gain KO and time-constants i. Arange break-points (poles, zeros or on for complex-conjugate poles) in ascending order ii Based on the term Ko(ju)Fk, determine: initial slope of the magnitude-response asymptote for low frequencies as F k 20 dB/dec (e.g....

A stirred tank flow reactor is operating in continuous mode
(shown below), and an exothermic (heat generating) chemical
reaction is taking place inside the reactor. The control objective
is to maintain the concentration of product at a desired value (set
point). The conversion of chemical reaction is highly dependent on
the reaction temperature. To maintain the reaction temperature at
the desired value, a cooling water jacket is used for the reactor.
The major input disturbance is fluctuation in the temperature...

spring relief disk 3. (40 pt.) A pressure cooker cooks a lot faster than an ordinary pan by maintaining a higher pressure and temperature inside. The lid of a pressure cooker is well sealed, and steam can escape only through an opening in the middle of the lid. The pressure relief valve consists of a spring-loaded disk that is positioned over this opening. Consider that a certain portion of a pressure cooker is initially filled with water and put on...
