- Based on these analyses , we see that the si - based quantum - dot laser has higher gain and differential gain , its threshold current is more lower and the threshold current is insensitive to temperature when si - based quantum - dot laser compares with normal semiconductor laser and quantum - well laser
分析表明，与普通激光器和量子阱激光器相比， si基量子点激光器有更高的增益和微分增益，阈值电流更低，阈值电流对温度更不敏感。 - 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。 - In this thesis , we demonstrate the study of si - based light emitting materials and its importance in si - based photonics integration . we discussed mainly the gain , differential gain , threshold current of si - based quantum - dot laser and the dependence of threshold current on temperature from discrete energy level of three - dimension confined quantum - dot and state density distribution of 5 - function
