摘要:实际的控制系统,有一个饱和特性。当控制变量达到某一值时,系统的输出变量不再生长时,系统进入饱和区。这就要求系统的控制变量,必须限制在一定范围内,有时会是有限的控制量的变化率。

最广泛使用的调节器控制规律是比例,积分,微分控制,简称为PID控制,也称为PID调节器。 PID控制器的出现已经近70年的历史,其结构简单,稳定性好,工作可靠,调整方便,并成为一个重要的工业控制技术进行了。当被控对象的结构和参数不能完全掌握,或缺乏精确的数学模型,控制理论是很难用其他技术,系统控制器的结构和参数必须依靠经验和现场调试来确定,当应用PID控制是最方便的。

The most widely used regulator control law is a proportional , integral, differential control , referred to as PID control , also known as PID regulator . The advent of the PID controller has been nearly 70 years of history , with its simple structure , good stability , reliable , easy to adjust and become a major industrial control technology a . When the structure and parameters of the controlled object can not fully grasp , or the lack of a precise mathematical model, control theory is difficult to use other technologies , the system controller structure and parameters must rely on experience and on-site commissioning to determine , when the application PID control is most convenient. That is, when we do not fully understand a system and the controlled object , or can not be an effective means of measurement to obtain the system parameters , the most suitable PID control . PID control , in practice there are PI and PD control . PID controller is based on the error of the system , using a proportional , integral , differential control amount is calculated for the control .


比例(P)控制比例控制是一种简单的控制。其控制器的输出与输入误差信号成比例关系。当只有比例控制时系统输出存在稳态误差(稳态误差)。

Proportional (P) control : Proportional control is a simple control. Its controller's output and input error signal proportional relationship . When only proportional control system output when there is steady-state error (Steady-state error).


比例调节的相称反应系统的偏差,一旦系统出了问题,比例控制调节立即减少偏差。比例的效果,并能加快调整,减少错误,但比重过大,因此,关闭系统的稳定性,甚至会导致系统不稳定。

Proportional regulation : a proportionate response system deviation , once the system has gone wrong , proportional control regulation to reduce immediate bias. Proportional effect, and can speed up the adjustment, reduce errors, but the proportion is too large , so that the stability of the system down , and even cause system instability.

Integral (I) control: integral control , the controller output and input error signal proportional to the integral relationship . For an automatic control system, if present , after entering the steady state error , the control system is called the steady-state error or simply a poor system (System with Steady-state Error). In order to eliminate the steady state error , the controller must introduce the " integral term ." Integral term of the error depends on the time integral , as time increases , the integral term will increase. Thus, even if the error is small , the integral term will increase with the increase of time , it pushes the output of the controller increases the steady-state error further reduced until it is equal to zero . Therefore, the proportional + integral (PI) controller, you can make the system after entering the no steady state error .

Integral regulation : Is the system to eliminate the steady state error , no gradient to improve . Because there is an error , integral control will be carried out until no difference , integral control stop , integral control outputs a constant value . Integral action depends on the strength of the integral time constant Ti, Ti is smaller, the stronger the integral action . On the contrary , the integral role of the weak Ti large , adding integral control allows th论文英语论文网提供整理,提供论文代写英语论文代写代写论文代写英语论文代写留学生论文代写英文论文留学生论文代写相关核心关键词搜索。
