For the system and requirements of Problem P10.39, determine the required compensator when the steady-state error for the ramp input must be equal to 0.02.
Problem P10.39
A unity feedback systeahas a plant
We desire that the phase margin be equal to 30°. For a ramp input r(t) = t, we want the steady-state error to be equal to 0.05. Design a lag compensator to satisfy the requirements. Verify the results.
What is the probability that a single randomly sampled battery of this type lasts longer than 100 minutes. Does this suggest that a charge-life exceeding 100 minutes would be unusual?
When 40 people used the Weight Watchers diet for one year, their weight losses had a standard deviation of 4.9 lb (based on data from "Comparision of the Atkins, Ornish, Weight Watchers, abd Zone Diets for Weight Loss and Heart Disease Reduction, ..
For a random sample of 12 observations, the sample mean was 407 and the sample standard deviation 6. Using the .01 significance level: State the decision rule.
Chi-square tests are great to show if distributions differ or if two variables interact in producing outcomes. What are some examples of variables that you might want to check using the chi-square tests? What would these results tell you?
A standard deviation of about $9000. Approximately what percentage of household incomes in this state is between $27,000 to $63,000/year? Show all work as to how this is obtained.
Use the frequency chart on the age of actors and when they won a prestigious award and construct a corresponding histogram.
Let X1,..., Xn be a random sample from a uniform distribution on [θ, θ + 1]. Find a 99% con?dence interval for θ, using an appropriate pivot.

An electric scale gives a reading equal to the true weight plus a random error that is normally distributed with mean 0 and standard deviation σ = .1 mg. Suppose that the results of five successive weighings of the same object are as follows: 3..

A group of students collected data at the Cedar Point amusement park and reported that the "wait time" to ride the "Top Thrill Dragster" roller coaster is consistently distributed within a range of 40 minutes to 90 minutes.
A study examines self-esteem and depression in children. A sample of 25 children with low self-esteem is given a standardized test for depression. The average score for the group is M=93.3.
