set (Control Design and Simulation Module, MathScript Function)
Member of the info class.
Syntax
SysOut = set(SysIn, infotype, infoval)
SysOut = set(SysIn, infotype_1, infoval_1, ..., infotype_n, infoval_n)
Description
Sets information to a linear time-invariant (LTI) system model. You can set numerator and denominator coefficient values to transfer function models. You can set zero and pole locations, as well as a gain value, to zero-pole-gain models. You can set A, B, C, and D matrices to state-space models. You can set delay information and sampling time to all model forms. You can set more than one information type and value simultaneously.
Inputs
Name | Description | ||||||||||||||||||||||||||
SysIn | Specifies an LTI model in transfer function, zero-pole-gain, or state-space form. | ||||||||||||||||||||||||||
infotype_n | Specifies the type of information you want to set to the SysIn model. You can specify more than one information type at a time. infotype is a string that can take the following values:
|
||||||||||||||||||||||||||
infoval_n | Specifies the value of the information you want to set to the SysIn model. You can specify more than one value simultaneously. The data type of the infoval input depends on the value you specify for the infotype input. If infotype is 'num', 'den', 'b', 'c', or 'd', infoval is a real scalar or real vector, depending on the number of elements you specify. If infotype is 'z' or 'p', infoval is a complex vector. If infotype is 'a' or 'k', 'infoval' is a real scalar or real matrix, depending on the number of inputs, outputs, or states of the model. If infotype is 'ts', infoval is a real scalar. If infotype is 'inputdelay', infoval is a real vector whose i-th element corresponds to the delay of the i-th input to the SysIn model. If infotype is 'outputdelay', infoval is a real vector whose j-th element corresponds to the delay of the j-th output from the SysIn model. If infotype is 'iodelay' or 'transdelay', infoval is a real matrix whose ij-th element corresponds to the delay between the i-th input and the j-th output of the SysIn model. |
Outputs
Name | Description |
SysOut | Returns an LTI model with the information and value(s) you specified in the infotype and infoval inputs. SysOut is a model in transfer function, zero-pole-gain, or state-space form. |
Examples
SysIn = tf(1, [0.2, 4])
SysOut = set(SysIn, 'num', [.05, 3], 'inputdelay', 0.8, 'ts', 0.1)
SysIn = ss(1, 1, 1, 0, 0.1)
SysOut = set(SysIn, 'c', 5)
