摘要：
A model for Chinese medicine sugar precipitation is designed, without considering crystal size distribution. Adaptive robust control algorithm is presented for the uncertain nonlinear system based on Lyapunov's stability theory. The kernel idea is model decomposition: adaptive control algorithm is designed for attenuating the parameter uncertainties; robust control algorithm is designed for eliminating the disturbance and unknown dynamics; feedback control algorithm is designed for dominating the nominal plant. The stability is proven and the output of system tracks the set point very well. The algorithm is applied to the sugar precipitation control of Chinese medicine solution. Simulation result upheld the significance of the proposed algorithm.
