The Auto LED die Mapping and Sorting System is a key manufacturing Equipment in LED production. This paper chooses the LED test system as experimental platform, based on which a precise and programmable multi-range digital Source-meter System (SMS) has been developed. In the embedded control part, a Self-organizing Fuzzy PID Controller (SFPID) is designed. a normalized acceleration as the indicator...
Nowadays, commercial lithium-ion (Li-ion) batteries are playing important roles as supplies for mobile phones, laptop computers and other electronics. In order to maximize the performance of Li-ion batteries, advanced charger is required. The main objective of an advanced battery charger includes short recharge times, high charging efficiencies and improved battery cycle life. This paper presents...
This paper presents a novel evolutionary algorithm based on a hybrid of Taguchi method and particle swarm optimization (PSO), and thus is called HTPSO. First, the nonlinear nano-positioning system is approximated by the Takagi-Sugeno (T-S) fuzzy model. Second, the parallel distributed compensation (PDC) is designed to control the piezoelectric system. Last, the parameters of the fuzzy controller are...
