Liang PEI,Liming WANG,Zhanying MA

Frontiers of Environmental Science & Engineering 2014, Volume 8, Issue 4,   Pages 503-509 doi: 10.1007/s11783-013-0540-1

Abstract: A mathematical model for the transport of Ce(IV) from hydrochloric acid solutions through dispersionIn this work, the system is considered to be in a transient state, and chemical reaction between Ce(IVThe experimental and simulated Ce(IV) extractions showed similar tendencies for a high Ce(IV) concentrationand acidity case.The model results indicate that high initial Ce(IV) concentrations and acidity bothhave detrimental effects on Ce(IV) extraction and stripping.

Principle and curve of planetary indexing cam mechanisms

LIU Ming-tao, ZHANG Ce, YANG Yu-hu

Frontiers of Mechanical Engineering 2006, Volume 1, Issue 4,   Pages 475-478 doi: 10.1007/s11465-006-0063-6

Abstract: A new type of planetary indexing cam mechanism called type !c is presented. The transmission principle of type !c is discussed. Based on the principle of formation of conjugate tooth contour, the equations of the cam s pitch curve are derived. The continuity and symmetry of the cam s pitch curve are also analyzed. It can be concluded that: 1) This type has no output institution so the output precision can be improved; 2) The asymmetrical two-ring structure is used to overcome dead point and its phase angle is equal to (π - 2π/n); 3) The continuous condition of the cam s pitch curve is that the average transmission ratio is -n in an intermittent motion period.

Posture control of a 3-RPS pneumatic parallel platform with parameter initialization and an adaptive robustmethod Article

Guo-liang TAO,Ce SHANG,De-yuan MENG,Chao-chao ZHOU

Frontiers of Information Technology & Electronic Engineering 2017, Volume 18, Issue 3,   Pages 303-316 doi: 10.1631/FITEE.1500353

Abstract: A control algorithm for a 3-RPS parallel platform driven by pneumatic cylinders is discussed. All cylinders are controlled by proportional directional valves while the kinematic and dynamic properties of the system are modeled. The method of adaptive robust control is applied to the controller using a back-stepping approach and online parameter estimation. To compensate for the uncertainty and the influence caused by estimations, a fast dynamic compensator is integrated in the controller design. To prevent any influence caused by the load applied to the moving platform changing in a practical working situation, the identification of parameters is taken as the initialization of unknown parameters in the controller, which can improve the adaptability of the algorithm. Using these methods, the response rate of the parameter estimation and control performance were improved significantly. The adverse effects of load and restriction forces were eliminated by the initialization and online estimation. Experiments under different situations illustrated the effectiveness of the adaptive robust controller with parameter initialization, approaching average tracking errors of less than 1%.
