Abstract

In this paper, the control problem of Multi-Input Multi-Output (MIMO) nonlinear Systems with unknown dynamics is proposed. A novel method based on the Sliding Mode with Time Delay Control (SMTDC) is proposed by combining a Sliding Mode Control (SMC) with saturation (sat) function and Time Delay Control (TDC). This method (SMTDC), allows chattering reduction on control inputs and estimates the amounts of unknown or unmodeled nonlinear dynamics and unexpected uncertainties and cancels them. This algorithm was simulated on the model of the ANAT robot arm system to demonstrate the effectiveness of the proposed design method.

未知动态多输入多输出非线性系统的滑模时滞控制
研究了具有未知动态特性的多输入多输出非线性系统的控制问题。提出了一种基于滑模带时滞控制(SMTDC)的新方法,该方法将滑模带饱和(sat)函数控制(SMC)与时滞控制(TDC)相结合。这种方法(SMTDC)可以减少控制输入的抖振,并估计未知或未建模的非线性动力学和意外不确定性的数量,并消除它们。在ANAT机械臂系统模型上对该算法进行了仿真,验证了所提设计方法的有效性。
