State space equation

Hi I have state space equation Xdott= (A-BK)X+BXref Where A is (3,3) matrix B(1,3), K(3,1) Xref is [3,1] How I can find X matrix as function to time or in other world find the position and speed in variable time

Thx

Hi rami,

you have an ODE with states X over T. You can solve them explicit with the Lambda-e-Approach (just recollecting) or you solve it nummerically with the help of ODE-functions. For the second way use doc ode45 in the commandline and read read read ;)

good luck, CN
