At present, monitoring of technical state of complicated technical objects under different attacks and destabilizing factors, aging, and dispersion of technological parameters is a crucial problem. Requirements to the quality, security, and reliability of complicated technical systems are consistently increased. In this chapter, we propose new method for adaptive control of technical states of the radio-electronic systems. This approach is based on the interval complex estimation of parameters, use of knowledge base of the critical and regular states, and also inner connections between the controlled parameters considering the false negative and false positive ratios. Multidimensional presentation of technical state of the controlled systems is possible using the accurate monitoring of technical states of the radio-electronic systems, increased accuracy and reliability of state identification, and extended possibilities of control and diagnostic equipment.
