摘　　要：基于小波变换的多分辨分析功能 ,对有约束广义预测控制的预测和控制时域在小波域进行分块压缩 ,降低了约束维数 。A generalized predictive control (GPC) algorithm with constraint handing properties is proposed, which retains computational simplicity. The constraint handing is achieved by formulating an infinite horizon receding problem. On line computational requirements for multi time scale systems are reduced substantially by wavelet. We show that the blocking and condensation technology is conveniently applied after expressing the GPC and constraint equation in terms of wavelet bases.
