In this paper, a new kind of quantum particle swarm algorithm for continuous space optimization is proposed, in which quantum computation is introduced into PSO. The particles can be described as superposition of multiple states. Quantum bits are updated by quantum rotation gates, and mutated by quantum non-gates. The numerical simulation results show that the new algorithm has better stability, global...
Projectiles in coil gun usually make one-way movement and move at a very high speed. The device would be fit for the application of oil pumping unit, as long as the projectiles can make reciprocating movement and move slower by adopting proper control methods. At present, during the production process of petroleum, the efficiency of the system is rather low. Energy dissipation takes a considerable...

Traditional oil pumping unit has the disadvantages such as inferior controllability and low efficiency, new types of motors are researched to take the place of the conventional pumping unit. The electromagnetic oil-pumping unit driven directly by linear motor is presented in this paper. The principle of nine-phase DC linear motor is proposed, and general structure is designed. Finally the small-scale...
