[Research on modeling and simulation of the system of position transformation mechanical ventilation].

The principle of Position Transformation Mechanical Ventilation (PTMV) was introduced briefly, and the mechanical structure and the intelligent control algorithm were studied. According to the principle and function requirement of PTMV, the mechanical structure of slip pole driven rocking chair(SPDRC) was proposed, the dynamics model of SPDRC was established, and the auto disturbance rejection controller was designed. The integrated model of control system was structured by using ADAMS and MATLAB, and the model validation and simulation were implemented.
