摘要
基于小波基函数的正交逼近特性及运算矩阵,提出了一种求解混合H2/H∞鲁棒控制问题的新方法。该方法利用离散小波快速算法的数值矩阵,将原问题转化为代数矩阵问题,避免计算耦合Riccati微分方程,适合于计算机求解。文中给出了计算实例,计算结果令人满意。
A new method for computing the mixed H_2/H_∞ robust problem is proposed based on the multi-scale multi-resolution approximation feature and the operation matrix of wavelets basis. This method changes the mixed H_2/H_∞ robust problem into an algebraic matrix equations problem using the numerical matrix of fast discrete wavelets transform. The procedure avoids computing a pair of cross-coupled Riccati equations, so it is simple and clear, and suitable to calculate by computer. Numerical examples show that the method is rational and effective.
