COMPLEX APPROACH TO IMPROVE DYNAMICS OF ALTERNATING AND DIRECT CURRENT ELECTRIC DRIVES BY METHODS POLYNOMIAL EQUATIONS AND DIAGRAMS QUALITY CONTROL

Synthesis of second order astatism speed controller for the system of two-mass vector-controlled asynchronous electric drive with non-linear and constant load are considered. Optimization of researched systems by the method of quality control diagrams by criterion a maximum of good quality and stability margin are made. Complex approach to improve dynamic characteristics of alternating and direct current electric drive, based on the gradual application of the methods of polynomial equations and quality control diagrams are realized.
