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. How to plot the bode plot of this transfer function with maple 15. Gj db 20 40 02040 0 9090180270 f hz 10 1 10 2 10 3 10 4 10 5. Combine multiple words with dashes, and seperate tags with spaces. 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. 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. In electrical engineering and control theory, a bode plot. Tags are words are used to describe and categorize your content. To interactively shape the openloop response using control system designer, use the bode editor. Setting the phase matching options so that at 1 rads the phase is near 750 degrees yields the second bode plot. It is usually a combination of a bode magnitude plot, expressing the magnitude usually in decibels of the frequency response, and a bode phase plot, expressing the phase shift as originally conceived by hendrik wade bode in the 1930s, the plot is an asymptotic.
Scribd is the worlds largest social reading and publishing site. For more information on analyzing linear models, see analyze results using linear analysis tool. The outputs mag and phase are 3d arrays similar to those produced by bode see the bode reference page. In the editor, you can adjust the openloop bandwidth and design to gain and phase. Bode diagram design is an interactive graphical method of modifying a compensator to achieve a specific openloop response loop shaping. Descargue como pdf, txt o lea en linea desde scribd. To do so, in the simulink window, in the apps gallery, click linearization manager to specify an analysis point for a signal, click the signal in the model. The first bode plot has a phase of 45 degrees at a frequency of 1 rads. In case of multioutput the outputs are plotted with different symbols. Nichols chart of frequency response matlab nichols. How to plot the bode plot of this transfer function with. The software adds the linearized model, linsys1, to the linear analysis workspace and generates a bode plot for the model. This matlab function creates a bode plot of the frequency response of a dynamic system model sys. Bode plot of frequency response, or magnitude and phase data.
