\( 13: 04 \) ?. 26 ?.?. \( 100 \% \) Project.pdf G4. An X-4 quadrotor flyer is designed as a small-sized unmanned autonomous vehicle (UAV) that flies mainly indoors and can help in search and recognizance missions. To minimize mechanical problems and for simplicity, this aircraft uses fixed pitch rotors with specially designed blades. Therefore, for thrust it is necessary to add a fifth propeller. A simplified design of the thrust control design can be modeled as in Figure below with \( G(s)=G_{c}(s) P(s) \) where \[ P(s)=\frac{1.90978\left(\frac{s}{0.43}+1\right)}{\left(\frac{s}{9.6}+1\right)\left(\frac{s}{0.54}+1\right)} \] represents the dynamies of the thruster rotor gain, the motor, and the battery dynamics. Initially, the system is designed using a proportional compensator given by \( G_{C}(s)=3 \) a. Calculate the resulting steady-state error for a unit step input. b. Design a lag compensator to yield half the steady-state error of the proportional compensator, without appreciably affecting the system's transient response.

A pollster believes that 20% of the voters in a certain area favor a bond issue. If 64 voters are randomly sampled from the large number of voters in this area, approximate the probability that the sampled fraction of voters favoring the bond issue will not differ from the true fraction by more than 0.04. (Round your answer to four decimal places.)

A rocket is launched from the top of a 50 foot cliff with an initial velocity of 120 feet per second. The height, h, of the rocket after t seconds is given by the equation $h = -16t^2 + 120t + 50$. How long after the rocket is launched will it be 20 feet from the ground?

A construction company is evaluating the purchase of a new excavator model for its projects. The market price of the new model is $71,000. The company plans to use the excavator for a period of 10 years. Considering an estimated general inflation rate of 4%, the annual operating expenses for the new excavator are expected to decrease due to improved efficiency, with the savings projected to increase by 6% each year. The company's Minimum Attractive Rate of Return (MARR) is 12% per year, representing the desired inflation-free interest rate. The analysis is based on a reference year of zero. The question at hand is: What should be the annual savings in the first year in order for the company to recover the investment cost through the associated savings? The analysis should be conducted using actual dollar values.
