PPD512 A10-15000 3BHE040375R1023 静态励磁系统

PPC380AE02该选择包括运算功能、控制功能、通信功能、编程功能、诊断功能和处理速度等特性的选择。

控制功能

控制功能包括PID控制运算、前馈补偿控制运算、比值控制运算等，应根据控制要求确定。可编程逻辑控制器主要用于顺序逻辑控制，因此，大多数场合常采用单回路或多回路控制器解决模拟量的控制，有时也采用专用的智能输入输出单元完成所需的控制功能，提高可编程逻辑控制器的处理速度和节省存储器容量。例如采用PID控制单元、高速计数器、带速度补偿的模拟单元、ASC码转换单元等。

PPC380AE02 The selection includes the selection of computing function, control function, communication function, programming function, diagnostic function and processing speed.

Control function

The control function includes PID control operation, feedforward compensation control operation, ratio control operation, etc., which should be determined according to the control requirements. Programmable logic controller is mainly used for sequential logic control, therefore, most occasions often use a single loop or multi-loop controller to solve the analog control, and sometimes also use a dedicated intelligent input and output unit to complete the required control functions, improve the processing speed of programmable logic controller and save memory capacity. For example, PID control unit, high-speed counter, analog unit with speed compensation, ASC code conversion unit, etc.
