 环传递函数
 The results of simulation tests show that the practical digital controller presented by authors is a reasonable control model for the microcomputer seam tracking system with leading sensor,because of its highest tracing accuracy (the tracing error<0.5 mm) and its simplest structure to simplify the calculating of the control variables (the close loop transfer function of the microcomputer control system equals 1). 这些数字控制器的仿真试验结果表明，本文提出的实用型数字控制器具有跟踪结构精度高（跟踪误差＜0．5mm），结构简单、计算方便（微机控制系统闭环传递函数＝1）等优点，因而是这类传感器超前检测式微机跟踪系统的比较合理的数字控制器。 短句来源 When these methods are employed,the zero and pole distribution of theopen loop transfer function G(s) must be given and the open loop pulse transfe-function G(z) oz the bilinear w-transfer function G(w) will be obtained. 在用这些方法时,常常是已知系统开环传递函数G(S)的零、极点分布,要求求出系统的开环脉冲传递函数G(Z)及双线性W 变换传递函数G(w),从而画出伯特图来。 短句来源 If closed loop transfer function of position inner loop is thought as typical two-order system, H2 robust control based on Smith predictor is adopted to solve the variation of long-time delay and pressing efficiency of thickness measuring. 在将位置内环的闭环传递函数等效为一个典型的二阶环节系统的情况下,针对厚度闭环中存在的厚度检测中的可变大时滞环节以及压下效率的变化问题,采用了基于Smith预估器的H_2鲁棒控制。 短句来源 Exploiting the new computation method of close—loop transfer function to get easily the PID loop’s close—loop transfer function. 开发了新的闭环传递函数计算方法,使闭环传递函数的求取变得容易。 短句来源 The closed loop transfer function matrix of such a system must be singular, so the closed loop transfer function should be assumed a singular matrix before the robust controller is designed. 考虑到此系统的闭环传递函数阵一定是奇异的 ,将闭环传递函数阵即补灵敏度函数设为奇异阵 ,设计出鲁棒控制器 . 短句来源 更多

By introducing appropriate weighting on the control signals, this method not only can achieve the target loop transfer function, but also can get a controller with relatively low gain and limited bandwidth. 提出了目标回路传递函数恢复的一种新的控制系统H∞/LTR设计方法,通过引入对控制量的加权,不仅可以保持LQR回路的特性,而且可以使控制器具有较低的增益和较小的带宽。 短句来源

 loop transfer function
 For MROC-based feedback loops, designed in order to achieve LQ optimal regulation, we characterize additive and multiplicative norm-bounded perturbations of the loop transfer function matrix which do not destabilize the closed-loop system. State space conditions, formulated in an appropriate parameter space, define a convex set containing all the stabilizing control gains that guarantee an upper bound on the ?∞-norm of the closed-loop transfer function. The controllers are designed in the operator space given the closed-loop transfer function. The procedure to find the controller transfer function is reduced to algebraic division of polynomials and produces the dependence of the closed-loop transfer function on the roots of the characteristic polynomial of the closed-loop system.
