| 摘 要： | 针对一般控制系统,利用微分几何中的曲线理论提出了形状变量、被控形状轨迹曲线和形状合同控制等概念.然后,针对一类具有双输入及二维形状变最的非线性系统,利用相对曲率概念和曲线论基本定理设计了三维平面形状合同控制器,这种形状合同控制器能够保证系统的被控形状轨迹曲线与参考轨迹曲线具有完全相同的形状.最后的仿真说明了所采用方法的有效性.

| Abstract: | Based on the curve theory in differential geometry, we introduce for general control systems the concepts of shape variable, the controlled shape-trace curve and the shape congruence control. By employing the signed curvature, we design a two-dimensional planar shape congruence controller for a class of nonlinear systems with binary input and binary shape variables. This controller ensures the shape of the controlled shape-trace curve to be the same as the shape of the reference trace curve. Simulation results show the validity of the method. |

| Keywords: | nonlinear system shape variable shape trace curve controlled shape congruence controller |
