| 中文摘要 |
| 针对参数未知、外部干扰未知并且带有输入、输出约束的离散时间仿射非线性系统,本文基于高阶干扰观测器的投影算法与模型预测控制和补偿控制相结合,提出了一种基于补偿控制的自适应模型预测控制方法.利用基于高阶干扰观测器的投影算法对未知参数和外部干扰同步估计,根据干扰观测值和参数估计值设计补偿控制量,使系统输入和输出满足约束条件,从而保证模型预测控制优化问题的可行性,并使系统的输出收敛到标称系统的输出.最后,将所提方法应用到电熔镁砂熔炼过程中电极电流控制的仿真实验中,通过仿真验证所提方法的有效性. |
| 英文摘要 |
| For discrete-time affine nonlinear systems with unknown system parameters, unknown external disturbances and input and output constraints, an adaptive model predictive control method based on compensation control is proposed by combining compensation control, parameter estimation and model predictive control. The projection algorithm based on high-order disturbance observer is used to estimate the unknown parameters and external disturbance synchronously. According to the disturbance observation values and parameter estimation values, the compensation control variables are designed to make the input and output of the system meet the constraints, thus ensuring the feasibility of the model predictive control optimization problem and making the output of the system converge to the output of the nominal system. Finally, the proposed method is applied to the simulation experiment of electrode current control in fused magnesia smelting process, and the effectiveness of the proposed method is verified by simulation. |
