控制系统中量值累积计算误差原因分析及解决方法

Accumulated Value Calculation Error Cause Analysis and Solution in Control System

工程中,由于量值(流量、电量)累积算法不够完善,会使量值在累积计算过程中产生较大误差。通过深入分析累积算法误差产生的原因,给出了如何避免较大累积误差产生的方法,并通过仿真验证了方法的有效性,对于量值的正确累积运算具有重要的指导意义。

ln engineering,because the value ﹙such as flow,electricity﹚ accumulation algorithm is not perfect,it can make the accumulated value have larger error.Through in-depth analysis of the error cause of accumulation algorithm,the method how to avoid the larger cumulative error is given,and the effectiveness of the method is also verified by simulation,which has im-portant guiding significance for the correct value accumulated operation.
