增量式PID控制在温控系统中的应用

温度的控制在科学实验和工业过程中极为普遍,具有典型的意义,而温控系统通常是时变的、非线性的、具有纯滞后的复杂大惯性系统,控制效果与采用的控制算法有很大的关系.针对这一问题,在温度控制实验系统中,设计了一种增量式PID控制算法实现了对温度的控制.通过实验表明,该算法的控制效果要优于传统的PID控制算法,对于工程实际应用具有较强的借鉴作用.

Application of Increasing PID Controlling Method in Temperature Controlling System

Temperature control is widely applied in scientific experiments and industrial processes.However,the temperature control system has characteristics of being nonlinear,time-varying and has hysteretic complicated large inertial system,and the effect of control is closely related to the algorithms adopted.In this paper,an experimental temperature control system is developed to meet the requirement of innovative ability training for mechatronic undergraduates.An increasing PID control algorithm is designed.The experimental results prove that the effect of the designed algorithm is better than the traditional PID algorithm.
