functionfromMatrices

Information

Syntax

dss = 'constructor'.fromMatrices(A, B, C, D)
dss = 'constructor'.fromMatrices(A, B, C, D, Ts, B2, method)

Description

This function constructs a DiscreteStateSpace record dss with

dss.A = A;
dss.B = B;
dss.C = C;
dss.D = D;
dss.B2 = B2;
dss.Ts = Ts;
dss.method = method;

i.e. the input-matrices are the system matrices of the discrete system. The default values of sample time Ts and discretization method method are

    Ts = 1
method = Modelica_LinearSystems2.Types.Method.Trapezoidal

respectively. See also fromMatrices2 where the inputs are the matrices of a continuous system which is to convert to discrete state space.

Example

  import dss=Modelica_LinearSystems2.DiscreteStateSpace;
  Real A[1,1] = [1];
  Real B[1,1] = [1];
  Real C[1,1] = [1];
  Real D[1,1] = [0];

public
  DiscreteStateSpace dss;

algorithm
  dss := dss.'constructor'.fromMatrices(A, B, C, D)  // or just: dss := dss(A, B, C, D, Ts=1, B2=[0], method=Modelica_LinearSystems2.Types.Method.Trapezoidal);
  // dss.A = [1]
  // dss.B = [1]
  // dss.C = [1]
  // dss.D = [0]
  // dss.B2 = [0]
  // dss.Ts = 1
  // dss.method = Modelica_LinearSystems2.Types.Method.Trapezoidal
