3.1前向通道的含义 体现了被测对象与系统相互联系的信号输入通道,原始参数输入通道。由于该通道中主要是传感器和与 传感器有关的信号调节、变换电路,故也可称为传感器接口通道

1 Intellectual property The Dutch legal system of intellectual property rights is highly determined by European legis lative initiatives. Both the European Directive on software protection and the European Directive on Data base protection have been implemented into Dutch law. This implied a Iment of the Copyright Law as well as the introduction of sui generis law on the protection for those databases that do not meet the requirement of under the Dutch Copyright

一个自动控制系统要能常的工作,它必须首 先是一个稳定的系统。也就是说,当系统受界 干扰后,虽然它的原有平衡状态相对稳定状态被破 坏,但在外部干扰去掉后仍有能力自动地在另新 的平衡状态(相对稳定状态下继续工作下去系统的 这一种本能通常叫做統的稳定性。例如常见的电 压自动调节系统中保持电机电压为恒定的能力电机

一、关税与贸易总协定的历史 关贸总协定(the General Agreements on Tariff and Trade,gatt)是一个国际性经济组 织,与国际货币基金组织、世界银行构成调节世界经贸关系的三大支柱

The quantity K2 is known as the Kalman gain. It is the optimum gain in the mean squared error sense. Substitute it into the expression for

The estimate of x based on N data points can then be made without reprocessing the first N, points. Their effect can be included simply by starting with pseudo observation which is equal to the estimate based on the first N points having a variance equal to the variance of the estimate based on N The same is true of the variance of the estimate based on N

The two middle terms are zero: fort>lo,n(t) and are uncorrelated becauset) is white(impulse correlation function) For=, n() has a finite effect on x()because n() is white. But the integral of a finite quantity over one point is zero
