MODELING DYNAMIC SYSTEMS with SIMULINK

by F Marquez

Simulink is a block diagram environment for multidomain simulation and Model-Based Design. It supports system-level design, simulation, automatic code generation, and continuous test and verification of embedded systems. Simulink provides a graphical editor, customizable block libraries, and solvers for modeling and simulating dynamic systems. It is integrated with MATLAB(R), enabling you to incorporate MATLAB algorithms into models and export simulation results to MATLAB for further analysis.Simulink is a graphical modeling and simulation environment for dynamic systems. A block can represent a physical component, a small system, or a function; an input/output relationship fully characterizes the block. The definition of a block is only complete with its inputs and outputs and this task relates to the goal of the model. For example, the cart velocity may be a natural choice as an output if the modeling goal does not involve its location. Simulink provides block libraries that are collections of blocks grouped by functionality. For example, to model a megaphone that simply multiplies its input by a constant, you would use a Gain block from the Math Operations library.In simulation, time progresses differently from a real clock. Each time step takes as much time as it takes to finish the computations for that time step, whether that time step represents a fraction of a second or a few years. Often, the effect of a component's input on its output is not instantaneous. For example, turning on a heater does not result in an instant change in temperature. Rather, this action provides input to a differential equation, and the history of the temperature (a state) is also a factor. When simulation requires solving a differential or difference equation, Simulink employs memory and numerical solvers to compute the state values for the time step.
