The absolute and relative stability of multi-machine is analyzed intuitionally using the open-loop frequency characteristic charts and the performance index of open-loop frequency domain for each decoupling single-machine 频域分析法在多机系统小扰动稳定方面的研究尚没有达到工程实用的要求。
Wp201 202 series isolation transformation module adopts miniature guide way type structure surface packing technique, has a great improved anti-interference ability of module, it can to transform analog signal such as temperature, pressure, flow, displacement, standard voltage and current and so on into isalated with it the standard voltage or current signal output and wide use to fields such as metallurgy, chemical industries, petroleum chemical, papermaking and printing dyeing, brewing, tobacco and aerospace base and so on . it may intuitionally indicates measuring value, can modify the parameter, easy to field debugging and operation 智能给定操作器具有万能分度号输入的位式控制表所有特点,自动时测量值与给定值比较,决定操作器输出的正转或反转,双屏数码管显示,上屏显示测量值,下屏显示给定值,手动时由按键操作决定正转或反转开关量输出,与电动执行机构配合可控制系统的液位或温度等。
