Choose K, z and p so that the closed-loop system G(s) has a maximum of 10% overshoot to a step input and a 1% settling time of no more than 1.5sec. Do not attempt any pole/zero cancellation! Recall that when a pole is very close to a zero, the effects of the two are nearly cancelled in the output. Hint: Review lecture notes on System Zeros. Verify your design using Matlab by plotting a step response of your closed-loop system. Print the step response and attach it to your homework

When using the ohmmeter function of a digital multimeter, the leads are placed in what position relative to the component being tested? a. parallel b. control c. series d. line

Air is to be cooled in the evaporator section of a refrigerator by passing it over a bank of 0.8-cm-outer-diameter and 0.4-m-long tubes inside which the refrigerant is evaporating at -20°c. air approaches the tube bank in the normal direction at 0°c and 1 atm with a mean velocity of 4 m/s. the tubes are arranged in-line with longitudinal and transverse pitches of sl- st 1.5 cm. there are 30 rows in the flow direction with 15 tubes in each row. determine (a) the refrigeration capacity of this system and (b) pressure drop across the tube bank. evaluate the air properties at an assumed mean temperature of -5°c and 1 atm. is this a good assumption?
