Description

This block implements a Discrete Second-Order Filter using State-Space equations. All computations are performed in single-precision floating-point format.

Mask Parameters

Use external synchronization source: When this option is selected, an input port for the sample time synchronization will be available. The external synchronization will have to be a pulse train with the same period as the sample time of the filter.

Inputs

u: This input must be a XFloat8_24 signal. It is the filter input signal.

rst: This input must be a UFix1_0 signal. When active, the internal synchronization source counter is reset.

Params: This input must be connected to the Second-Order Filter Unpacking block. It contains the filter parameters as set from the Second-Order Filter control block located in the RT-LAB simulation model.

Sync: This input must be a UFix1_0 signal. It is available only if the "Use external synchronization source" option is selected, and must be a pulse train with a period equal to the controller sample time, as set in the Second-Order Filter control block located in the RT-LAB simulation model.

Outputs

y: This output is the filtered signal, and is in single floating-point numerical format (XFloat8_24).
