Download file to see previous pages As noticed in Lab 3 the stability, response, as well as all features of the response of a system, are governed by system poles’ location. Poles’ location can differ if a factor in the system is altered (mostly gain (K).The poles usually move with a pattern as the gain is varied in the system, which can then be used in establishing system features for every value of K.

This is facilitated by Root Locus which enables us to calculate and graphically plot all likely K values within a system. System pole movement plotting facilitates response features for the definite gain to be read straight off the graph, which is extremely helpful as it indicates the system’s response for all potential K values.

For a basic feedback control system as indicated below, the root locus is determined; where the closed-loop transfer function is represented by N(s) is the numerator polynomial and D(s) is the denominator polynomial or the distinctive equation. As indicated by figure 1 below, a system can be designed to consistently respond and as needed by the use of root locus. Radial lines radiating from the source are lines of steady dampening whereby. This, therefore, can be utilized in determining percentage overshoot which gives the ratio of real to imaginary elements; this implies the lines are also lines of constant overshoot. Making an assumption that the coupling of the load and motor is perfect, then the friction co-efficient (bs)=0 as well as the spring constant (K), modeling of the drive can be done by the following equation; Section B of the first Experiment needs the utilization of a filter in the control system which is utilized in the reduction of noise. RSVP has alternatives for no filter, first as well as second-order filters. Variations between RSVL and MATLAB emanated from correctness in values. This is mostly due to the utilization of the virtual oscilloscope in the measurement of the features together with the noise and indefinite simulated measurement in RSVL while MATLAB determines exact response values.    ...Download file to see next pagesRead More

Matlab problem

...? Matlab programing Introduction This task was conducted in a bid to find a solution to the problem of optimizing combination of E12 resistors in series. Resistors are components of electricity which obstruct the flow of electric current and in the process make the current do actual work like lighting, heating, producing sound, magnetism and the like. This task tries to come up with a programming solution to the problem of combining resistors in a manner that would minimize the cost incurred in setting up the entire set up. The task is to come up with a Matlab program which shall be able to lay out the most optimal mode of combining E12 resistors so as to form a desired value of resistance. It is to see to it that the resistors used...

Utilization Management

Concurrent utilization however has certain strengths as well as some weaknesses. The strengths of the concurrent utilization review pertain to the fact that the concurrent utilization review can highlight the differences and discrepancies that exit in the different business processes across an industry. Moreover the concurrent utilization theory can also highlight the responsibility and accountability factor in the different processes and how it is being handled by the different firms. (Schlesinger & Gray, 1997) The other advantage of the concurrent approach for utilization review is that multiple entities can be thoroughly and comprehensively reviewed in terms of their workflows and utilization strategies. The effect of the diff...

Locus of Control

...Running Head: Locus of Control Locus of Control, Optimism Levels, and Perseverance during a Frustration Task December 3, 2008 Locus of Control is compared with degree of optimism or pessimism using GESS and ICI inventories. Seventeen subjects completed the questionnaires and scores ranged from 64 to 149 for the GESS and 67 to 139 for the ICI. A high correlation between Internal Locus of Control and Optimism was demonstrated. The second part of this study measured perseverance during a Frustration Task in relation to Locus of Control. Two sets of five puzzles were randomly assigned. One set included five solvable puzzles, the Non-Frustration task, and the second set had two solvable and three unsolvable puzzles, the Frustration task...

In #2.b z provides the integral of the function over the interval [-1, 1] by using trapezoidal numerical integration, while in #2.c z1 provides the integral over the same interval of the piecewise polynomial pp.
The above program is a function which uses the Composite Simpson’s 1/3 rule to integrate a given arbitrary integral f from a lower limit a to an upper limit b over a known interval n. The function outputs the Composite Simpson’s rule sum, which is the integral of the function

This I feel is inappropriate to a great extent as Kevin, has been concentrating on improving the production process alone without taking into consideration the inventories, budgets and even the manual roll – out of the products. In order to create a more efficient process, it would be more effective and efficient if the company recorded the raw materials when it enters the premises. The budget can also be calculated using the production plan and this will lead to an easier mode of access to the information of the inventories...

... for standard deviation and the third line for regression line of PV = aA1indicator + aA0. 2.3. Procedure The first step of developing this system involves the identification of the variables to use in the regression analysis. In this program, the two variables identified are PV and Indication of the solar irradiation. The next step is to develop models for linear regression to determine the relationship between the dependent and the independent variable (Chatterjee and Hadi 57). The third step is to develop a matlab source code file containing the model and able to access the source of data to be analysed. The fourth step is to test the program and remove errors.

...Matlab Assignment: Problem 4 First Last Introduction Road construction involves leveling of the land. This cannot be achieved without removal of earth material as opposed to building a road along the slope of the hill. When a road passes through a hilly terrain, the road is designed in such way to minimize excess earth materials to be brought into the site, or be taken from the site. Thus the total areas (or volume) change before and after the road construction remains minimum, but the shape has been changed. Fig 1.Longitude section of the hilly terrain. A road needs to be built through a hilly terrain at a sloping angle of not more than 10 degrees with minimal material wastage. The various measurements (height of hill and distance across...

...COMPUTING AND PROGRAMMING WITH MATLAB By Computing and Programming with MATLAB INTRODUCTION Two scenarios are being investigated, one of linear horizontal motion and that of linear vertical acceleration. In traveling through air, the beetle will experience upwards and gravitational force acting downwards. Therefore, to estimate the final velocity of the beetle we need to incorporate the drag force due to air resistance and the gravitational component of the velocity for the beetle to fall one mile below. Determination of the Velocity of the porsch is by empirical and mathematical equations of linear motion. In solving for the freefall velocity of the beetle, we shall make use of the MATLAB high level programming language. In these review...
