An automated guided vehicle (AGV) can be considered as an automated mobile conveyor designed to transport materials. Most AGVs require some type of guide path. The steering stability of the guidance control system has not been fully solved. The slight "snaking" of the AGV about the track generally has been acceptable, although it indicates instability of the steering guidance control system [9].
Most AGVs have a specification of maximum speed of about 1 m/s, although in practice they are usually operated at half that speed. In a fully automated manufacturing environment, there should be few personnel in the production area; therefore, the AGV should be able to be run at full speed. As the speed of the AGV increases, so does the difficulty in designing stable and smooth tracking controls.
A steering system for an AGV is shown in Figure P10.30, where τ1 = 40 ms and τ2 = 1 ms. We require that the velocity constant Kv be 100 so that the steady state error for a ramp input will be 1 % of the slope of the ramp. Neglect τ2 and design a lead compensator so that the phase margin is
Attempt to obtain the two limiting cases for phase margin, and compare your results for the two designs by determining the actual percent overshoot and settling time for a step input.
According to the American Hotel and Motel Association (AHMA), women are expected to account for half of all business travelers by the year 2002. To attract these women business travelers, the AHMA found that 70% offer hair dryers in the bathrooms..
Find the probability using the Poisson distribution.
Let P be the transition matrix of an ergodic Markov chain. Let x be any column vector such that Px = x. Let M be the maximum value of the components of x. Assume thatxi = M . Show that if pij > 0 then xj = M . Use this to prove that x must ..
Also include information about the number of participants you would assess and how you would go about estimating effect size and statistical power (when relevant).
a factory makes light bulbs. over a long period 4 of them are found to be faulty. a random sample of 100 light bulbs is
Assume that a random sample is used to est. a population proportion p. find margin of error E that corresponds to the given statistics and confidence level. 98% confidence sample size 1166 of whic are 35% successes. What is margin of error?
When are differences between average or actual results important and how can you or your department decide whether or not the observed differences over time are important?
discuss the implications of magnitude from 0 to 1 sign or - and probability versus causality for the correlation
Because its fixtures are attached to the ceiling, the bulbs are rather cumbersome to replace, and Shop-Mart is looking into the possibility of switching to Phipps bulbs, which cost the same. A sample of Phipps bulbs lasted an average of 2080 hours..
What is the chi-square goodness of a fit test? What is its purpose? What does it measure? Is there a way of telling when the test is over?
