The Gilles & Retzbach model of a distillation column, the system model includes the dynamics of a boiler, is driven by the inputs of steam flow and the flow rate of the vapour side stream, and the measurements are the temperature changes at two different locations along the column. The state space model is given by: X = -30.3 0.00012 0 0 0 00 6.02 0 0 -3.77 0 0 -2.80 0 0 x+ 6.15 0 0 0 0 0 3.04 0.052 u y = 0 0 0 -7.3 0 0 0 -25.0

9.- Consider that the serial velocity is given by: baud_rate=Fosc/k(n+1) With k and n (integers) It is required to communicate at 1200 bps with a 1MHz clock and K=16 n=5. The error expression iserror=(real_baud_rate - ideal_baud_rate)/ideal_baud_rate What is the % error in this case?

1) In a RC charging circuit, given R = 100 Kohm, Supply voltage = 12 V and voltage across thecapacitor is 5.8 V after time t = 15 ms. Find the value of the capacitor used. 2) If R = 10 Kohm and C = 10 µF, find the frequency of the astable multivibrator? Draw itsoutput waveform for Vcc = + 5 V.

A heat transfer process has the following transfer func-tion between a temperatureT(in∘C) and an inlet flow rate q where the time constants have units of minutes:T′(s)/Q′(s)=3(1−s)/{s(2s+1)} If the flow rate varies sinusoidally with an amplitude of 2 L/min and a period of 0.5 min, what is the amplitude of the tempera-ture signal after the transients have died out?

Draw the signal flowchart of the system shown below. Using the flowchart, you can calculate C (s).find.

22 - When the unit step function is applied to the input of the control system given below, the peak time of the output signal is 0.47 s and the settlement time is 0.91 s. It is also known that the steady state error of the system is 10% for the same input. So what is the natural frequency of the system? calculate.A) 9B) 5C) 6D) 7E) 8

During a vibration measurement experiment in the Mechanical Engineering Department at Hacettepe University, a piezoelectric accelerometer output is given by this mathemtaical equation: a (t) = 1 + 4 sin(43.98t) + 7sin(100.53t) in gravity acceleration (g) value. a)      Determine the frequencies (in Hz) contained in the signal. Round your results to nearest integer value. b)     What is the minimum sampling rate to avoid aliasing? c)      Sketch clearly the frequency spectrum if the signal is sampled at 15 Hz. d)     Now, the signal is filtered with a low-pass Butterworth filter to remove the maximum frequency component. It is desired to attenuate the amplitude of this component to at least 5 % of its value. If the sampling rate is now 20 Hz, what will be the order of the filter? e)      If the blue one is our signal, then what is red and green ones? Write down the mathematical relation between the three signals? (Use labels as blue, red and green signal.)
