Control algorithmIntelligent PID control algorithm [56] is the control algorithm base on conventional PID control algorithm for the object that has characteristic of delay, timevarying and nonlinear systems, and in different segments has different algorithm. It has both BangBang fast control and the lag control stability control and antijamming capability.As intelligent PID control algorithm is not dependent on the mathematical model, and is not sensitive to changes in parameters, therefore is more suitable for field use.. PID algorithm to achieve the figuresIn the analog system, the expression of PID algorithm is: （1） Discrete equation (1), digital form of differential equations instead of the continuous system differential equations, differential and integral can be expressed using sum and incremental form: （2） （3）Under the principle of recursion may write PID output expression with k: （4）In the equation (4), =/T is integral coefficient, =/T d is differential coefficient. So the differential equation of PID can be expressed: （5）In the equation (5), is control value, is deviation, is proportion factor, is integration control factor, is differential control factor.Once the system generates error, PID controller immediately works to make the object reduce errors, the strength and feebleness of control function depend on proportion factor , and its limitation is existing static error for control objects with selfbalancing ability. Increasing value can reduces static errors, but the big value has led to the dynamic performance of the system weaker.Integral memory error helps the system eliminate static errors, but the limitation of integral role is that makes a control system have lag characteristics. If the integral role is too strong, it would make dynamic quality of the object weaker and lead to the closedloop system instability. The differential error can get the trend of error change, and increasing differential control factoraccelerate the system response, but it will be sensitive to interference, and reducing the antijamming ability of the system.. Intelligent PID control rulesBecause the PID algorithm gets the desired effect only when the system model parameters are nondenaturing, when a okay PID controller is applied in the model parameters timechanging system, its capability can bee difference which parameters are adjusted well, and even instability. Therefore, the intelligent PID controller parameters can only be got by many times calculation according to the factsituation. A system allows for the maximum deviation , minimum deviation , so the PID control rules of system as follow:Rule 1:IF︱︳ THEN = (k)。所以它應(yīng)該在物質(zhì)情況和控制要求中進(jìn)行折衷的選擇。規(guī)則3：IF︱︳ THEN =+ []+。3 控制算法智能PID控制算法[5 6]是基于常規(guī)PID控制的控制算法，這種算法對對象具有延遲,時變和非線性系統(tǒng)的特點(diǎn)和在不同環(huán)節(jié)有不同的算法。在粗糙的部分通過脫脂爐后,然后通過一個封閉的輸送帶進(jìn)入水平連續(xù)燒結(jié)爐。本附件為封面，封面上不得出現(xiàn)頁碼。計(jì)算機(jī)電腦和智能控制理論的發(fā)展為復(fù)雜控制方法和動態(tài)不確定度系統(tǒng)控制提供了一種新方法。微分誤差能獲得誤差變化趨勢，增長微分控制因素可以加快系統(tǒng)響應(yīng)，但是它對干擾敏感和降低系統(tǒng)抗干擾的能力。當(dāng)讀和寫參數(shù)時，首先，我們應(yīng)知道參數(shù)的代碼。伴隨著智能PID控制， P，I，D的設(shè)置能直接影響PID控制的結(jié)果，如此這些參數(shù)與控制系統(tǒng)本身有了緊密的聯(lián)系。 automation, 2004, Vol. 20, , pp. 820 (in Chines
