For tunable control design blocks, the function evaluates the model at its current value for both plotting and returning frequency response data. For uncertain control design blocks, the function plots the nominal value and random samples of the model. When you use output arguments, the function returns frequency response data for the nominal model only.

Frequency-response data models such as frd models. For such models, the function plots the response at frequencies defined in the model. Identified LTI models, such as idtf , idss , or idproc models. For such models, the function can also plot confidence intervals and return standard deviations of the frequency response.

See Bode Plot of Identified Model. If sys is an array of models, the function plots the frequency responses of all models in the array on the same axes. Line style, marker, and color, specified as a string or vector of one, two, or three characters. The characters can appear in any order. You do not need to specify all three characteristics line style, marker, and color. For example, if you omit the line style and specify the marker, then the plot shows only the marker and no line.

For more information about configuring this argument, see the LineSpec input argument of the plot function. Example: 'r--' specifies a red dashed line. Example: 'y' specifies a yellow line. If w is a vector of frequencies, then the function computes the response at each specified frequency. For example, use logspace to generate a row vector with logarithmically spaced frequency values. The vector w can contain both positive and negative frequencies.

For models with complex coefficients, if you specify a frequency range of [ w min , w max ] for your plot, then in:. Log frequency scale, the plot frequency limits are set to [ w min , w max ] and the plot shows two branches, one for positive frequencies [ w min , w max ] and one for negative frequencies [— w max ,— w min ]. Linear frequency scale, the plot frequency limits are set to [— w max , w max ] and the plot shows a single branch with a symmetric frequency range centered at a frequency value of zero.

Magnitude of the system response in absolute units, returned as a 3-D array. For SISO systems, mag 1,1,k gives the magnitude of the response at the k th frequency in w or wout. For an example, see Obtain Magnitude and Phase Data. For MIMO systems, mag i,j,k gives the magnitude of the response at the k th frequency from the j th input to the i th output. Stable Unstable Probabilistic Undetermined. Answer Detailed Solution Below Option 3 : 0.

Answer Detailed Solution Below Option 3 : phase cross-over. Concept: Gain margin GM : The gain margin of the system defines by how much the system gain can be increased so that the system moves on the edge of stability. Answer Detailed Solution Below Option 3 : all frequencies.

Answer Detailed Solution Below Option 2 : error constant. The magnitude of the Bode plot at low frequencies in dB is 20 log K P The steady state error for step input i. Answer Detailed Solution Below Option 1 : 1. The order of the system The magnitude of the system The type of the system The error in the system. Analysis: Slope of log magnitude curve in bode plot depends on the number of poles at origin i.

Answer Detailed Solution Below Option 3 : 3 and 4. Concept: The LTI system is said to be stable if it satisfies following two conditions 1. If the system is excited by bounded input the output must be bounded. The stability is classified into the following ways: Absolute stability : Here system is stable for all values of system parameters. For the relative stability, both Gain margin and Phase margin is required. Answer Detailed Solution Below Option 4 : an unstable, type-1 system.

So, there is a zero at the origin. Let assume a transfer function that follows the above two conditions. Exam Preparation Simplified Learn, practice, analyse and improve. Testbook Edu Solutions Pvt. Our Apps. Coulson Plot Generator v.
