| 6. | The innovative ideas in this paper is to replace the linear fixed - gain pid controller for a nonlinear pid controller . based on the step response curves of conventional control system , we analyze the ideal variety of three gains in different times and construct the simulated curves of proportional , intergral and derivative gain . the controllers has considered all sorts of imperceptible factors affecting the servo performances in a lpmsm servo system , which include the parametric uncertainties brought by the changes of the mobile mass , the dynamitic performance of the system and the size of input . to solve the problem of so many unknown parameters , we use transmit arithmetic to find the parameters which are fit for the system . to keep the robust and stable performance 本文的创新之处在于,将传统的固定增益的pid控制器用非线性pid控制器来代替,并在此基础上,就一般控制系统的阶跃响应曲线,分析了在不同响应时间阶段pid的三个增益调节参数的理想变化情况,并根据这些理想变化,分别给出了比例、积分、微分增益参数的一种连续的非线性拟和函数。在分析双位置环时,仔细考虑了能使系统性能变坏的各种因素,如系统的动态性能及控制出入能量的大小等等。 |
| 7. | So it can be used as one part of the industrial process control or a valuable associated software for analyzing and simulating control systems . iterative learning control based on the study of robotic control adjusts control input repetitively with simple learning control algorithms , using input and output data of the previous operation over a fixed time interval , until perfect tracking is achieved 在机器人背景下发展起来的迭代学习控制对解决具有某种重复运动(运行)轨迹跟踪问题具有独特的能力,本文研究的目的是利用迭代学习控制理论为一般控制系统的设计性能优良的控制器,以期扩大迭代学习控制的应用领域。 |
