A computer-oriented procedure for efficient stability analysis of very large systems was developed by modifying a method due to Mikhailov. The method allows pure time delays in the system model. The state variable model of the system is used, and the computational procedure is tailored to take advantage of the sparesness of the system matrices that are applicable for many systems. The practicality of the procedure has been demonstrated in the analysis of several systems, the largest of which consisted of a 553rd order model of a multistage flash evaporator plant.
