Mechatronics: Principles and Applications
Mechatronics is a core subject for engineers, combining elements of mechanical and electronic engineering into the development of computer-controlled mechanical devices such as DVD players or anti-lock braking systems. This book is the most comprehensive text available for both mechanical and electrical engineering students and will enable them to engage fully with all stages of mechatronic system design. It offers broader and more integrated coverage than other books in the field with practical examples, case studies and exercises throughout and an Instructor's Manual. A further key feature of the book is its integrated coverage of programming the PIC microcontroller, and the use of MATLAB and Simulink programming and modelling, along with code files for downloading from the accompanying website.
* Integrated coverage of PIC microcontroller programming, MATLAB and Simulink modelling
* Fully developed student exercises, detailed practical examples
* Accompanying website with Instructor's Manual, downloadable code and image bank

Page 26 - Mesh Current Analysis Method 1 . Define each mesh current consistently. We shall always define mesh currents clockwise, for convenience. 2. Apply KVL around each mesh, expressing each voltage in terms of one or more mesh currents. 3. Solve the resulting linear system of equations with mesh currents as the independent variables. In mesh analysis, it is important to be consistent in choosing the direction of current flow. To avoid confusion in writing the circuit equations, mesh currents will be defined...
Page 21 - ... voltage at each node as an independent variable. One of the nodes is selected as a reference node (usually, but not necessarily, ground), and each of the other node voltages is referenced to this node. Once each node voltage is defined, Ohm's law may be applied between any two adjacent nodes in order to determine the current flowing in each branch. In the node voltage method, each branch current is expressed in terms of one or more node voltages; thus, currents do not explicitly enter into the...
Page 22 - Figure 5.3.2 illustrates this procedure. The systematic application of this method to a circuit with n nodes would lead to writing n linear equations. However, one of the node voltages is the reference voltage and is therefore already known, since it is usually assumed to be zero. Thus, we can write n - 1 independent linear equations in the n - 1 independent variables (the node voltages). Nodal analysis provides the minimum number of equations required to solve the circuit, since any branch voltage...
Page 31 - In studying node voltage and mesh current analysis, you may have observed that there is a certain correspondence (called duality) between current sources and voltage sources, on the one hand, and parallel and series circuits, on the other. This duality appears again very clearly in the analysis of equivalent circuits: it will shortly be shown that equivalent circuits fall into one of two classes, involving either a voltage or a current source and, respectively, either series or parallel resistors,...
Page 2 - Mechatronics is the synergistic combination of precision mechanical engineering, electronic control and systems thinking in the design of products and manufacturing processes.
Page 31 - Zero all voltage and current sources. 3. Compute the total resistance between load terminals, with the load removed. This resistance is equivalent to that which would be encountered by a current source connected to the circuit in place of the load.
Page 31 - Norton equivalent circuit consists of finding the equivalent resistance presented by the circuit at its terminals. This is done by setting all sources in the circuit equal to zero and computing the effective resistance between terminals. The voltage and current sources present in the circuit are set to zero...
Page 22 - Reference all other node voltages to this node. 2. Define the remaining n — 1 node voltages as the independent variables. 3. Apply KCL at each of the n — 1 nodes, expressing each current in terms of the adjacent node voltages. 4. Solve the linear system of n — 1 equations in n — 1 unknowns.
Page xiii - Mechatronics in its fundamental form can be regarded as the fusion of mechanical and electrical disciplines in modern engineering processes. It is a relatively new concept relating to the design of systems, devices and products aimed at achieving an optimal balance between basic mechanical structure and its overall control.
