Model identification method based on GASA strategy for AC variable frequency speed regulation system

Method of. modeling using the intelligent optimization algorithms is discussed for AC variable frequency speed regulation system. In order to solve the problem of interference free in open-loop control, a speed close loop is proposed. Using inverter drive motor and single chip unit in control decision, a speed close-loop control system is formed. Mathematical model of the control system is established using Genetic Algorithms and Simulated Annealing algorithms (GASA). Experimental results show the advantage of new hybrid optimization strategy with GASA.
