一些先进PID控制方法比较

Some kinds of advanced PID control methods compared

PID控制是最早发展起来的控制策略之一,由于其算法简单,鲁棒性好和可靠性高,被广泛应用于工业过程控制,尤其适用于可建立精确数学模型的确定性控制系统。在实际生产现场中,由于受到参数整定方法烦杂的困扰,常规PID控制器参数往往整定不良、性能欠佳,对运行工况的适应性很差。近年来出现了许多新型PID控制器,如智能型PID自整定控制器,模糊PID控制器等等。

PID control is one of the earliest development of the control strategy, due to its simple algorism, robustness and high reliability. It is widely used in the industrial process control, in particular, it can be applied to established a precise mathematical model of certainty control system. In actual field production, as determined by the complicated parameters＇methods troubled, Conventional PID controller＇parameters are often poor, poor performa rice and poor adaptability to working conditions. In recent years, many new PID controllers have come up, intelligent self-tuning PID controller, fuzzy PID controtlers, etc.
