Magnitude and phase are displayed, respectively, on logarithmic and linear scales. Setting the phase matching options so that at 1 rads the phase is near 750 degrees yields the second bode plot. P bodeoptions returns a default set of plot options for use with the bodeplot. How do i position the legend window in a bode plot with phase. This is referred to as the frequency domain behavior of a system. Bode plots can be shown for every 20sim model through linearization. Modelica in this forum you should post problems that you have while modelling systems with modelica. However, you can linearize the system around some operating point and look at the response of the linearized model.

If sys is a multiinput, multioutput mimo model, then bode produces an array of bode plots, each plot showing the frequency response of one io pair. The first bode plot has a phase of 45 degrees at a frequency of 1 rads. Bode diagram design is an interactive graphical method of modifying a compensator to achieve a specific openloop response loop shaping. The software linearizes the portion of the model between the linearization input and output at the default simulation time of 0, specified in snapshot times parameter in the block parameters dialog box, and plots the bode magnitude and phase. Therefore, a bode plot does not exist for nonlinear systems. If done correctly, you should see the screen below. Find voutvin assume you have the following parameters and try to draw the bode plots.

During linearization you are asked to enter the input variable and output variable for which linearization should be performed. Plot the linear system characteristics by clicking in the plot window alternatively, you can simulate the model from the model window. The watertank system block represents the plant in this control system and includes all of the system nonlinearities to specify the portion of the model to linearize, first open the linearization tab.
