Терминальное диагностирование дискретных динамических систем

Abstract

Introduction: The known works on test diagnostics of dynamic systems discuss the methods of diagnostics based on special test signals. However, these methods are often too complicated or unsafe (delta functions, jumps, etc). The challenge is to develop a method for testing dynamic systems which would provide a natural test motion of the system, for example, within specified bounds. Such a movement uses terminal control, so the diagnostics can be called terminal. Purpose: The goal is to examine the test diagnostics of linear discrete dynamic systems, using predefned terminal control as a test signal. Methods: We used the discrete system control theory which allowed us to build formulas for obtaining control of the system motion within given bounds. Results: We have developed a method for test diagnostics of discrete dynamic systems. The essence of the method is that using the calculated terminal control, the system comes into a state with the desired output signals. Due to this, the diagnostic criteria are rather simple: you just need to check the required output signals. The obtained results allow you to perform test diagnostics of discrete dynamic systems, which differs from the known methods because the test motion is a natural motion of the system within the given bounds.
