J. Cent. South Univ. Technol. (2009) 16: 0608-0613 DOI: 10.1007/s11771-009-0101-8 Control strategy for pneumatic rotary position servo systems based on feed forward compensation pole-placement... such as inherent non-linearity and variations of system parameters with working points. In order to improve the dynamic performance of the system, feed forward compensation self-tuning pole-placement......
Article ID: 1003-6326(2005)05-1125-05 Effect of deformation temperature and strain rate on semi-solid deformation behavior of spray-formed Al-70%Si alloys ZHANG Di(张 迪)1, YANG Bin(杨 滨)1... of the deformation temperature, strain rate and the microstructure were studied. Two strain rates(1s-1and 0.1s-1) and six deformation temperatures (600℃, 720℃ , 780℃, 900℃, 1000℃ and 1100℃) were chosen......
