Crops require consistent fertilization and spraying in order to maintain high yields. Traditionally this was done manually, with vehicles, or even via airplane. These methods are not only inefficient, and burdensome, but they can be very costly as well.

To increase safety and provide cost-effective work among the farmers, you are assigned to change the manual fertilizer spraying method to automatic fertilizer spraying method by using a drone. Note that there are two ways to fly a drone which is, manual and automatic. In order to perform automatic closed loop control system, automatic control must be take place.

Automatic control in this context means you will use waypoints to fly your drones. You need to control the drone’s height (level) and speed and also take into account the disturbances.

The design of automatic closed loop control system are comparatively complex than the manual ones. Such system takes feedback from output and performs the required action accordingly. The entire construction requires a sensor for taking input, some sort of controller which performs the action and a feedback taken from the output. 

 

Your design report should include (for height and speed control):

 

1. Introduction

a. System background (briefly explain on how to control a drone / how to fly a drone)

b. Justification of using automatic closed loop control rather manual control.

2. Identify all the variables involved

a. Controlled variable

b. Manipulated variable

c. Disturbances

3. Identify all the elements/instruments used

a. Controller

b. Final Control Element

c. Process/System

d. Sensor

4. Draw equivalent signal block diagram for the system

5. Explain the closed loop control system

6. Sketch the expected dynamic response

7. Briefly explain the advantages of automatic control in industry

8. Conclusion

1. The objective of simulation is to verify and optimize the design.

Simulation can idealize a circuit. The objective of measurement is

to experimentally confirm the specifications. Measurements must

consider all non-idealities.

a. Describe completely the definition of the Common

Mode Rejection Ratio (CMRR) of an operational

amplifier. Recommend a circuit to measure the CMRR.

Use MULTISIM to conduct the measurements of

CMRR. Provide the plot of the CMRR (in dB) versus

Frequency (Hz) to prove the efficacy of the OPAMP.

(15 Marks)

b. What do you understand by the term “slew rate” of an

operational amplifier? Recommend a circuit to

measure this parameter and provide complete

measurement of this parameter using the MULTISIM

environment.

(15 Marks)

 

2. Design an operational amplifier circuit that performs the

mathematical operation of integration with respect to time; that is,

its output voltage is proportional to the input voltage integrated

over time..

(5 Marks)

a. Explain fully the operation of the circuit and derive its

input/output characteristic equation.

(10 Marks)

b. Using MULTISIM show the performance of the circuit

when the input was impressed with the following

waveforms.

i. Square Wave

ii. Triangular Wave

iii. Sine Wave

(10 Marks)

c. Show that if the input is a sine wave of varying

frequency the OPAMP integrator performs like an

active low-pass filter.

(5 Marks)

3. An oscillator is the basic element of all AC signal sources and

generates sinusoidal signals of known frequency and amplitude.

It is one of the basic and useful instruments used in electrical

and electronic measurement. Oscillators are used in many

electronics circuits and systems providing the central clock

signal that controls the sequential operation of the entire

system.

a. Describe the operation of an OPAMP-based oscillator

using the concept of a basic oscillator feedback

circuit. Your description must include all pertinent

equations relating the overall closed loop gain and

the open-loop and feedback gain

(10 Marks)

b. Figure 1 shows the complete schematic diagram of a

variable frequency COLPITTS Oscillator. Use the

MULTISIM platform to simulate the operation of this

oscillator as you vary the values of the inductor, ????,

from 1???????? to 62????????. What is the gain of the oscillator?

(3 Marks)

i. Tabulate the output frequencies versus the

various inductor values.

(7 Marks)

ii. Show the output waveforms as displayed on

the oscilloscope for ten selected

frequencies.

(10 Marks)

iii. Show the output waveforms as displayed on

the spectrum analyzer of the output

amplitude versus frequency.

(10 Marks)

 Using Multisim, design a system by which a control signal of 4 to 20 mA is converted into a force of 200 to 1000N. Use a pneumatic actuator and specify the required diaphragm area if the pressure output is to be in the range of 20 to 100kPa. An I/P converter is available that converts 0 to 5 V into 20 to 100 kPa. A block diagraph of the system is shown below.

I need to deliver a lab report and a quick powerpoint presentation. and I need someone fast that can help me. I have all the information available in this website and its the same information on both documents (lab report and powerpoint presentation).

So first for the lab report I need you to copy all the information from here:

https://engineering.ucdenver.edu/docs/librariesprovider29/college-of-engineering-and-applied-science/sp2020-capstone/elec7-reportfb6f7ce5302864d9a5bfff0a001ce385.pdf?sfvrsn=3a4718b9_2

And put it together as if was my lab report. I go to Florida State University so I need you to erase all information from the original regarding that is from colorado and replace it for florida state. So basically you are copying all the information in a new word document and just replacing Colorado university to Florida state university. (Please I need some creativity on the decoration)

The only thing is that I need a new presentation page similar to the one in the link (first page of the lab report). But you have to put on top Florida State University on top and the logo. and replace the names for this ones:

Andres Bravo: 786-537-1521 / ab13bb@my.fsu.edu

Camila Cayre: 787-903-6959 / cc25cc@my.fsu.edu

Hassem Na: 954-937-7748 / ha90na@my.fsu.edu

Patrick Beverly: 571-265-3000 / pa12ly@my.fsu.edu

At the end of the report there are resumes. Just ignore that part.

For the presentation go here:

https://engineering.ucdenver.edu/docs/librariesprovider29/college-of-engineering-and-applied-science/sp2020-capstone/elec7-presentation.pdf?sfvrsn=1c291fb9_2

Same thing for the presentation. Replace everything that says University of colorado to Florida State University. Put on the same exact information for the presentation and replace the names.

Andres Bravo: 786-537-1521 / ab13bb@my.fsu.edu

Camila Cayre: 787-903-6959 / cc25cc@my.fsu.edu

Hassem Na: 954-937-7748 / ha90na@my.fsu.edu

Patrick Beverly: 571-265-3000 / pa12ly@my.fsu.edu

If you can be creative with the decoration I would appreciate it a lot. I will tip you and give you my best review and on top of that I can give you another easy task.
