 Hybrid Atom Search Particle Swarm Optimization, HASPSO, combines Atom Search Optimization and Particle Swarm Optimization to achieve better performance than either algorithm alone. It was tested on two real-world engineering problems, the design of a proportional integral derivative controller for an automatic voltage regulator and a doubly-fed induction generator-based wind turbine system. The results showed that HASPSO outperformed both Atom Search Optimization and Particle Swarm Optimization in terms of convergent speed and quality of solution. Additionally, it did not increase the computational cost significantly compared to other competing methods. This article was authored by Davut Izzy, Sir Dari Kincey, and Abdelazim G. Hussian.
