SINT – Simple integrator

Block SymbolLicensing group: STANDARD
PIC

Function Description
The SINT block implements a discrete integrator described by the following difference equation

yk = yk1 + TS 2Ti(uk + uk1),

where TS is the block execution period and Ti is the integral time constant. If Ti = 0, the block realize summation by following equation

yk = yk1 + uk.

If Ti < 0, the block behaviour is undefined. If yk falls out of the saturation limits ymin and ymax, the output and state of the block are appropriately modified.

For more complex tasks, consider using the INTE block, which provides extended functionality.
