The implementation of undergraduate enterprise education demands not only the reform of education and instruction, but also the rapid adjustment of each aspect of higher academies in order to adapt and promote it.
At present ,guiding by the law of market-oriented economy as well as national macroscopic regulates policy,the industrial structure and scale,its competition mode in domestic architecture & construction industry is on the rapid adjustment.
A predetermined PID control algorithm is proposed in this essay and applied to temperature control systems Experimental results show that thereis almost no override control in the heating stage,and no impact in the turning point of the designed temperature curve The perfomance of the system in controlling is improved by its rapid adjustment and high stability
Major causes that have led to this achievement are as follows: rapid adjustment of en- terprise structure, rectification of the financial order, development of hi-tech industry, encouragement to foreign investment, and inspiration of national spirit.
A method and a test device of air control drying were introduced. Conditional selection of double condenser and evaporater heat pump system was combined with rapid adjustment of rotation of compreser to adjust temperature and humidity of circulational air in drying system. Automatic control of different ratios including air composition was completed by using Expert PID adjustnent method.
