Computauion method for the real-time control problems in differential-algebraic systems

In this paper, a real-time computation method for the control problems in differential algebraic systems is presented. The errors of the method are estimated, and the relation between the sampling stepsize and the controlled errors is analyzed. The stability analysis is done for a model problem, and the stability region is ploted which gives the range of the sampling stepsizes with which the stability of control process is guaranteed.
