学会不同搜索法（最速下降法，共轭梯度法，牛顿法，拟牛顿法）的计算步骤； 比较不同搜索法（最速下降法，共轭梯度法，牛顿法，拟牛顿法）的优缺点。 (Institute of the different search method (steepest descent method, conjugate gradient method, Newton method, quasi-Newton method) for calculating steps compare different search method (steepest descent method, conjugate gradient method, Newton method, quasi-Newton method) the advantages and disadvantages.)

PID参数的整定就是合理的选择PID三参数。从系统的稳定性、响应速度，超调量和稳态精度等各方面考虑问题，三参数的作用如下：(PID parameter setting is the reasonable choice of three parameters of PID. From the system stability and response speed, overshoot and steady state accuracy and so on various aspects to consider problem, the role of the three parameters are as follows:)
