Computer-aided synthesis of qualitative uncertain control systems

The present paper suggests principally a new approach to the solution of one of the most actual problems of the modern automatic control theory-robust control systems investigation, namely the new method of synthesis of linear single-parameter uncertainty systems, satisfying specified quality requirements, has been worked out. This method is based on the circular root-locus field application. The system of programmes for PC has been worked out on the basis of above mentioned method, which can be successfully used for the computer-aided design (CAD) of robust automatic control systems. The above described methods may be successfully applied to computer-aided investigations of both single-parameter uncertain control systems with preset quality characteristics and dynamic systems with multiparameter uncertainties
