Abstract:An adaptive control (AC) strategy for internal grinding with power sensor is proposed.The strategy consists of control strategy of grinding without empty travel,fuzzy control strategy of grinding with constant power,and state monitoring control strategy of grinding wheel.The fuzzy control strategy with constant power is discussed emphatically.

Abstract:This paper discusses the effect of spiral laminae of polar materials on the stiffness of laminates and gives out the relation between spiral angle and equivalent elastic constants of the spiral laminates including asymmetric stresses and coupled stresses.It is concluded that the appropriate choice of the spiral angle of laminae can greatly enhance the stiffness of laminates.

Abstract:This paper first analyse the interrupted Bernoullis input processes and its superposition process and then give the purameter computational methods of approximate MMPP for ATM Multiplexer.

Abstract:The linear time invariant vibration system is analyzed by Continuous Wavelet Transform(CWT),the relationship of wavelet transform of output signal with the pulse response of system and input signal is put forward.As an exapmle,the wavelet transform of the output signal of system with single degree of freedom is calculated and compared with the direct wavelet transform result of the actual output signal,it shows that the two results are in complete agreement.

Abstract:Through the analysis in this paper,the optimum relation of the discharging current peak interval t m ,the discharging loop equivalent inductance L and equivalent resistance R is obtained.This paper analyze the original discharging loop equivalent inductance L ,which provides an effective method for adjustment and selection of inductance L to realize the optimization energy saving design of the welding machine.
