AC drive systems have been widely accepted for industrial applications. In general, they take the advantages of a higher power density and a higher efficiency than DC drive systems. This paper presents a novel chaotic-speed control of split-phase induction motor drives, especially for application to cooling fans. Based on the state vector analysis of the system, the d–qaxis model of the split phase induction motor is deduced. It reveals the periodicity and chaos for various system parameters. Mathematical analysis, computer simulation and experimental results are given to testify the proposed chaotic-speed fan.
