美国自动控制学界有两个规模较大的学术年会,一叫联合自动控制会议(JACC),另一叫决策与控制会议(CDC)。前者是由美国AIAA、AIChE、ASME、IEEE等学会轮流主办的,后者则由美国IEEE的控制系统学会和SIAM联合主办。通常,此两会议的论文报告人和参加者并不仅限于美国国内的学者,也包括不少其他各国的学者。最近一些年内,由于种种原因,JACC的水平有所下降,会议呈现不景气现象。因而自1982年起,JACC将由ACC(美国控制会议)取代,并由美国自动控制协会(AACC)主办。从1982年ACC的分会专题的内容看,该会仍象 There are two large academic conferences in the American automatic control community, one called the Joint Automation Conference (JACC) and the other called the Decision and Control Conference (CDC). The former is hosted by the AIAA, AIChE, ASME, IEEE and other institutes in turn. The latter is jointly organized by the American IEEE Institute of Control Systems and SIAM. In general, the conference speakers and participants for the two conferences are not limited to scholars within the United States, but also include scholars from many other countries. In recent years, due to various reasons, the level of JACC has declined, and the meeting has shown a slump. Since 1982, JACC will be replaced by the ACC (American Control Conference) and hosted by the American Association of Automatic Control (AACC). According to the contents of the chapters of the ACC in 1982, the society still looks like it
