摘要: 结合系统优化和参数估计的修改二步法(MTS),提出了单参数在线修正模型的非线性优化控制自适应方法。根据Lyapunov稳定性定理,给出了MTS法稳定收敛的最优协调增益K的在线计算方法,大大加快了算法的收敛速度,以甲醇制甲醛生产优化控制为例,仿真结果表明,该方法是有效的。Abstract: A non-linear adaptive optimizing control method is presented, in which the model is corrected on-line by modifing single model parameter based on the modified two-step method of system optimization and parameter estimation. On the basis of the Lyapunov stabilty theorem, the calculating method of the optimum coordinating gain on-line is put forward, which makes the algorithm stable and quick in convergence. Simulation results show that the method is effective.
