代码说明:

  回归分析中,检验自变量的重要性,将变量一个一个引入引入变量的条件是其偏回归平方和经检验时显著的,在引入新变量的同时,对已入选的变量逐个检验,将不显著的变量剔除。(The importance of the independent variables of regression analysis, test, introducing variable is introduced one by one into the condition of variable is the partial regression sum of squares in significantly after inspection, and at the same time of introducing new variables, for the selected variables one by one test, will not be significant variables.)

  • Fuzzy-PID-dual-mode-control-system
    交流位置伺服系统因其存在参数时变、负载扰动以及电机的非线性等缺点, 很难为其建立准确的模型. 模糊( fuzzy)控制具有无需建立被控对象的数学模型、鲁棒性好等 优点,但稳态精度差. 将模糊控制和PID 控制相结合,设计了Fuzzy-PID 双模控制器. 在论域内 用不同的控制方式分段实现控制,这样就综合了模糊控制和PID 控制的优点,克服了各自的缺 点. 该控制器结构简单、易于实现. 在半闭环交流位置伺服系统上所做的实验表明,采用Fuzzy- PID 双模控制器与采用经典PID 控制器相比,阶跃响应的调整时间减少了33. 7 ,并且无超 调,轨迹跟踪误差减小了47. 2 .(AC servo system because of the presence of parameter variations, load disturbances and non-linear motors and other shortcomings, it is difficult to establish accurate models for fuzzy (fuzzy) control without having to build a mathematical model of controlled object, robustness and good However, steady-state accuracy is poor. fuzzy control and PID control are combined to design a dual-mode Fuzzy-PID controller in the sub-region to achieve control on the different control methods, so that a combination of fuzzy control and PID control advantages to overcome their disadvantages. simply the controller structure, easy to implement. experiments on semi-closed loop AC servo system did show that the Fuzzy-PID controller is compared with the classic dual-mode PID controller, step response The adjustment time is reduced by 33.7 , and no overshoot, tracking error is reduced 47.2 .)
