After building a model of the system, the next thing is to run the model, the simulation results are obtained. Complete the process of running a simulation is divided into three steps: setting simulation parameters, simulation analysis and simulation results start.

First, setting simulation parameters and selection of solver

Set the simulation parameters and the choice of solver, select the Simulation menu under the Parameters command will pop up a dialog box that the main simulation parameters, parameters of three pages Management simulation.

The Solver page, it allows the user to set the start and end time, choice of solver, solver parameters and choose some output options.

Workspace I/O page is input management model from the MATLAB space and its output.

Diagnostics page, a warning message allows the user to select the Simulink displayed in the simulation of the grade.

1, Solver.

This page can be set: Simulation of the start and end time; choose the solver, and set its parameters; select output.

The simulation time: note here the concept of time and the real time is not the same, just the computer simulation of the time in a representation, such as the simulation time of 10 seconds, if the sampling step is 0.1, you need to perform a 100 step, if the step size is reduced, the sampling points increase, so the actual execution time will increase. The general simulation start time is set to 0, and the end time according to different factors and the choice of. In general, the implementation of a simulation to be time-consuming depends on many factors, including the complexity of the model, and the choice of step size solver, computer clock speed etc..

Simulation model: simulation step size selection mode specifies the user first drop-down option box behind Type, available Variable-step (variable step size) and Fixed-step (fixed step method). Variable step
