随着计算机的推广应用,描述系统的数学方法也有所改变。在经典调节理论中,线性定常系统所采用的微分方程、传递函数和拉氏变换,而在离散系统中则由差分方程、脉冲传递函数和Z变换所代替。这里仅将计算机如何完成PID调节规律作番介绍,希望能对读者有所助益。经典调节理论中的PID调节规律的微分方程式,可表示为:
With the popularization and application of computers, the mathematical method of describing the system has also changed. In classical regulation theory, the differential equations, transfer functions and Laplace transforms used in linear stationary systems are replaced by the difference equations, impulse transfer functions and Z-transformations in discrete systems. Here only how to complete the computer regulation of PID regulation for Fan introduction, I hope to help readers. The classical regulation theory of PID regulation of the differential equation, can be expressed as:
