In this section we consider modeling a few common nonlinear sys- tems with interesting behaviors in Simulink. There are essentially nonlinear phenomena that can take place only in the presence of nonlinearity; hence they cannot be described or predicted by linear models. 363 Chapter 10 Electromechanical and Mechanical Systems. The first linear motor was produced by Charles Wheatstone in 1845. Finally we will derive a two-state discrete Kalman filter for smoothing out sensor/process noise, and simulate the entire system in Simulink. Block diagrams for system models.

Mathworks, creators of MATLA & Simulink, provide extensive online documentation for Simulink that can be accessed using the MATLA help system. In Simulink, systems are drawn on screen as block diagrams. A linear system of the form Ax = b (1) arising from a real-life application may or may not admit a solution, that is, a vector x that satis es this equation exactly. Simulink is integrated with MATLAB and data can be easily transferred between the programs. There is so much online documentation that not many people have the time or inclination to read all of it. The first example is a low-pass RC Circuit that is often used as a filter. The system consists of a mass attached to a spring and damper. : Addison Wesley Pdf_module_version 0. • Linear systems • Simulation • Modeling uncertainty. 5.
