Although he speaks of the Far East between the 15th and 18th centuries as a single world-economy, he says it in fact comprised three "gigantic world-economies: Islam, overlooking the Indian Ocean from the Red Sea and the Persian Gulf, and controlling the deserts stretching across Asia from Arabia to China; India, whose influence extended throughout the India Ocean, both east and west of Cape Comorin; and China, at once a great territorial power- striking deep into the heart of Asia-and a maritime force, controlling the seas and countries bordering the Pacific."

In order to eliminate the influence caused by the nonminimum phase characteristic of a common Boost DC／DC converter, Viswanathan K has proposed a novel tristate Boost DC／DC converter. For enhancing performance, the statespace averaging model of this converter was first presented in this paper. Due to the nonlinear nature in this model, an inputoutput feedback linearization technique was adopted, and a complete controllable linear system was obtained. Then a statefeedback control strategy was designed based on this linear system. Simulation results show that the proposed control strategy can assure constant output voltage in a wide range, so as to realize the stability of the system during large fluctuation of power supply and load disturbance. Good dynamic performance can also be achieved.
