【Abstract】 In order to overcome the problem of the nonlinearity , large time delay and high jamming in the concentrate procedure of the production of Chinese traditional medicine, DMC-PID cascade control algorithm is applied . Gain the ends: compensating the time-delay , improving the ability of anti -jamming. Simulation result and the running system have shown the proposed approach possesses good robustness property and good dynamic control effectiveness, which is effective for adaptive control of nonlinear system.更多还原
