复合量控制系统的工程设计

The Engineering for Control System of Composed Variables

由于工业过程的实际对控制不断提出新的挑战，使得过程控制领域中新的控制思路和手段也层出不穷。现以汽包三冲量水位控制为１个引例，导出复合量控制系统的几条工程设计准则。

With new challenges to instrument engineers put forward continually from real industrial process,new control ideas and methods in the area of process control are emerging in an endless stream.An introductory example is level control system of three pulses for boiler.Several engineering principles of control systems for composed variables are introduced.
