Systems of resistance

Define what are the systems of resistance, and provide some understanding by answering the following questions:

What symptoms of resistance to change have you experienced? Have you experienced both active and passive forms? Have you experienced them as a resistor

yourself (as a recipient of change)? Have you experienced them as someone responsible for the management of change (as an initiator of change)?
Which of the various reasons for resisting change do you believe to be the most common? What are your “top three” in this regard?
Which of the various reasons for resisting change do you believe to be the most difficult to deal with (as a manager)? What are your “top three” in this

regard?
When senior managers resist change at the strategic level, they are in a position to cause more damage than employees resisting changes at the operational

level. Have you worked in a company where you believe that management resistance to change may have existed? As a manager yourself, what would you try to do

to prevent this from happening?
Which approach to the management of resistance attracts you? What is the reason for your choice? For example, is it because you think it to be the most

effective or does it also relate to a view that you have about how people should be managed?

Automatic control engineering question

1-) Students who design a balance robot for the Digital Control Systems course control the robot they have developed with the negative feedback system shown

in the figure.

Transfer function of the balance robot 𝐺(𝑠) = 1/(𝑠^2*(𝑠+2))

a. A proportional controller, indicated by 𝐺𝑐 (𝑠) = 𝐾 (𝐾> 0), was preferred to control the system. Does this robot stay in balance when the unit step function

is applied to the system’s input? Prove the reason by drawing the root-place-curve graph.

b. This time, it is desired to control the system using a PD, Proportional + Derivative type controller 𝐺𝑐 (𝑠) = 𝐾 (𝑠 + 𝑎) (𝑎, 𝐾> 0). Determine the range that a

robot will receive so that this robot can stay in balance against the unit step input.

c. By taking 𝑎 = 1 on the PD controller in (b), the closed loop system Show the positions of the poles on the graph in the s-plane for 𝐾> 0.

d. The dominant poles of the system using the controller in (c) Calculate the value of the K gain so that it can produce a 52% maximum overhead versus unit

input.

e. In order for this system’s steady state error to be a finite value other than 0, determine an appropriate input and calculate the steady state error to be

generated by the controller in option (c).

2-) As seen on the figure, the polar curve of the control system has been graphed according to 𝑤 ≅ 0

and 𝑤 ≅ ∞ for K = 1. It is known that the given system is a minimum-phase system. In addition, the

table shows the angular frequency of the system, and the reel and imaginer components of the

system at the point is giv

a. Complete the polar curve of this system and obtain the Nyquist diagram.

b. b. Perform stability analysis using the Nyquist graph.

c. Please determine the order of the system by explaining the reason.

d. Please find the gain margin, the phase margin, the gain pass frequency and phase pass

frequency by using Nyquist diagram and the table.

e. Determine the stability of the system using the calculated gain margin and phase margin

Annotated Bibliography = 30 points. ESI Learning Outcomes above. You will be writing an annotated bibliography for this course on a topic of your choice within the context of animal tool-use. An annotated bibliography is an expanded version of a regular bibliography (list of sources at the end of a research paper or book). It contains a paragraph (between two to five sentences) under each bibliographical entry summarizing the source content and explaining how or why the source is important for your chosen question. The aim of this annotated bibliography is for you to locate, read carefully and choose 10 pertinent primary scientific papers that may contain useful information and ideas on your topic. You will have to extract and present key information from them that provide a variety of perspectives on your question or demonstrate the evolution of your topic. You will have to compare or contrast this work with another you have cited, or explain how this work illuminates your topic. Use the extracted information ethically and responsibly (ESI Learning Outcomes). Cite the articles using the appropriate style and according to the guidelines given in class. Please submit your annotated bibliography digitally on Blackboard on May 7 no later than 6pm. Do not submit paper copies. This is a very strict deadline, and you will not be able to upload to Blackboard after this time. You should start the process of submitting your annotated bibliography early enough in-case of technical issues. Prof. Harmand will only accept assignments submitted in Microsoft Word or PDF format. Students are not permitted to re- write and re-submit their assignment in order to try to improve their marks after the due time.
     

Police Suicide in the United States

This course is called Research Methodology in Public Safety Administration. The paper requires a topic with some research. Eventually, the topic will
be tied to a complete research paper.
