介绍了一种基于系统特征数据的控制器设计算法.该算法仅根据被控对象的输入、输出采样数据,按照卷积定理计算出被控对象的单位脉冲响应作为系统的特征数据;在控制量约束条件下,根据特征数据以最速响应为控制目标规划出输出参考数据和最速控制律;然后根据控制目标和最速控制律的要求计算出理想控制器的特征数据;最后,根据控制器的特征数据辨识出线性控制器参数.仿真结果表明,控制结果具有最速参考控制的特征.
A controller design algorithm based on system characteristic data is introduced. The algorithm only outputs sampled data according to the input of the controlled object and calculates the unit impulse response of the controlled object as the characteristic data of the system according to the convolution theorem. Under the constraint conditions, the output reference data and the steepest control law are planned based on the characteristic data with the steepest response as the control target. Then the characteristic data of the ideal controller is calculated according to the requirements of the control target and the steepest control law. Finally, according to the characteristic data of the controller The linear controller parameters are identified.The simulation results show that the control results have the characteristics of steepest reference control.
