Can I Simulate MIMO(Multi-Input Multi-Output) Models in LabVIEW?

Primary Software: LabVIEW Toolkits>>PID Control Toolkit
Primary Software Version: 6.0
Primary Software Fixed Version: N/A
Secondary Software: N/A

Problem: I want to simulate MIMO (Multi-Input Multi-Output) models given in state-space form in LabVIEW. Are there any VIs available that perform this simulation?

Solution: Yes, LabVIEW's PID Control Toolset includes a State-Space VI that can be used to simulate MIMO models given in state-space form. MIMO systems are usually represented by

dx(t)/dt = Ax(t) + Bu(t)

y(t) = Cx(t) + Du(t)

where
  • x is the state vector
  • u and y are the input and the output vectors
  • A, B, C, and D are the state-space matrices

The State-Space VI calculates the new output and the internal states when given the state-space representation, the initial condition, and the input vectors. If the PID Control Toolset is installed, the State-Space VI is available on the Control»Advanced»Continuous Linear palette.

To get more information about using PID Control Toolset VIs to simulate physical systems, please refer to the PID Control Toolset User Manual linked below.
