针对厌氧消化过程难以建模、系统参数复杂等难点，提出了一种由稳定子控制与补偿子控制组成的且仅依赖系统输出的循环迭代无模型自适应控制器（composed recursive model free controller ，CRMFC），并借助特殊的非线性比例积分（nonlinear proportional-integral ，NPI）控制器对所提出的 CRMFC 进行了 Matlab/Simulink 的数值仿真以验证控制方法的性能，研究结果对厌氧消化过程的研究具有较大理论价值和工程应用前景。

Under the scheme that anaerobic digestion process is a complex nonlinear process difficult to model and with many pa-rameters difficult to be identified,we propose a composed recursive model free controller (CRMFC)which relies only on plant output and is composed of stabilization and compensation sub-controls.Finally,compared with a special kind of nonlinear propor-tional-integral controller,the effectiveness of the proposed method is validated via Matlab/Simulink based numerical results.Our study is of theoretical value of application in engineering for future research of anaerobic digestion process.
