There are four PI controllers in induction motor vector control system when identifying motor speed using MRAS. Parameter tuning of PI controllers will influence system performance directly. To overcome the difficulty of simultaneous parameter tuning for the PI controllers, Quantum Genetic Algorithm (QGA) was used to optimize PI parameters in each loop. A fitness function is designed in this paper...Show More
This paper presents a novel video encoding algorithm using the technique of Hybrid Vector Quantization (HVQ). Two modes of operations are defined in the encoder part, i.e. intra-mode and inter-mode. A blended algorithm based on Mean Coding and Conventional VQ (MCCVQ) using an intra-codebook is adopted for the intra-mode of operation. In the inter-mode of operation, no-encode sub-mode is for static...Show More
