Incorporate delays within the model instead.Ĭontrol Design and Simulation: (Hex 0xFFFF5CB7) The inputs of this VI must be discrete models without time delays. The PID problem might include linear inequalities that cannot be solved, or the numerical search might lack sufficient resolution.Ĭontrol Design and Simulation: (Hex 0xFFFF5CAC) The interior points of the stable set of PID gains are infeasible.Ĭontrol Design and Simulation: (Hex 0xFFFF5CAD) The stable set of PID gains is empty because the K3 interval is infeasible.Ĭontrol Design and Simulation: (Hex 0xFFFF5CB4) The input model must be proper.Ĭontrol Design and Simulation: (Hex 0xFFFF5CB5) The input state-space models must be SISO.Ĭontrol Design and Simulation: (Hex 0xFFFF5CB6) The inputs of this VI must be discrete models without time delays. Below are all of the Error Codes that belong to the Control Design and Simulation Error Code Family (see Error List for list of Families).Ĭontrol Design and Simulation: (Hex 0xFFFF5CAB) The set of interior points within the stable set of PID gains is empty.
