taylors approximation meaning in Chinese
泰勒近似
Examples
- The stress and local stability constraints are transformed into movable lower bounds of sizes . an inverse variable xt = ? is inducted , and the objective function is expanded as second order taylor approximation while the displacement constriction is expanded as first order taylor approximation . the lemke algorithm is used to get the final design result
把复杂的应力约束和局部稳定约束转化为动态尺寸约束，引入倒变量x _ i 1 / a _ i将目标函数展开为二阶近似，将位移约束用莫尔积分化为一阶近似，用对偶规划方法将原问题化为等价的二次规划问题，调用lemke算法，求得最优设计结果。 - This dissertation presented two new methods of robust adaptive track control for a class of mimo strong nonlinear system with external disturbance . one method makes use of taylor approximation principle to linearize the mimo strong nonlinear system at the ideal equilibrium point , meanwhile external disturbance is considered , and then designs two on - line neural network controller respectively , which can dynamically compensate the high order items of taylor series and the control signals at ideal equilibrium point under the drive of state error between linear and nonlinear system . a linear feedback controller obtained by pole assignment and two on - line neural network act on the practical mimo high nonlinear system together , guaranteeing the whole system robust stable and tracking the specified signal ; the other method designs three on - line neural networks for this class of system
本文对于一类含有外部扰动的多输入多输出( mimo )强非线性系统，提出了两种新的鲁棒自适应跟踪控制方法，第一种利用了taylor近似的原理，在考虑了外部扰动的情况下，将mimo强非线性系统在理想平衡点处线性化，分别设计了两个在线神经网络控制器，在线性和非线性系统之间的状态误差驱动下动态补偿系统的taylor近似高阶项及理想平衡点处的控制信号，满足极点配置方法的线性反馈控制器和两个在线神经网络联合作用于实际的被控mimo强非线性系统，在保证整个系统鲁棒稳定性的情况下，能够跟踪给定的指令信号；另一种方法是针对这类系统设计了3个在线神经网络，分别实时抵消这类非线性系统中的非线性部分、与控制量耦合的非线性项以及外部扰动，使得受控系统的输出可以完全跟踪给定输入参考信号。
