To improve the stability and accuracy of temperature control in pellet grill. this article proposes a method that applies a Fuzzy PID controller optimized with Improved Particle Swarm Optimization (IPSO). Techniques such as Circle mapping are introduced to enhance the convergence speed and efficacy of the particle swarm algorithm (PSO). The optimized particle swarm algorithm is used f... https://www.unitedssports.shop/product-category/hockey-skates-intermediate-performance/
