摘要:
针对传统PID算法在进行温度控制时存在超调量和控制误差较大的问题,提出一种改进的PID算法,用于小区域局部温度控制.为了避免系统操作和外界环境噪声引起的干扰,引入一阶低通滤波器,与常规PID一起构成复合控制.同时,在控制调节过程中,加入积分限幅和微分分离操作,进一步优化控制效果.仿真实验表明:改进PID算法能有效避免噪声对控制过程的影响,控制误差较小,满足小区域局部温控的要求.
Abstract:
For the problem that the overshoot and large control error existing in the temperature control when using the traditional PID algorithm, an improved PID algorithm for small local temperature control is proposed. To avoid the interference caused by system operations and the external environment noise, a first-order low-pass filter is introduced and is constructed compound control together with conventional PID. At the same time, in order to further optimize the control performance, the integral limiter and differential separation are added in the control and regulation process. The simulation results show that the improved PID algorithm can effectively avoid the effect of noise on the control process. The control error is small, and can meet the requirements of the local temperature control in small regions.
