In detail, by using operator based robust right coprime factorization approach, the control system design structures including feedforward and feedback controllers for both SISO and MIMO nonlinear uncertain systems are given, *** which, the controller design includes the information of PI hysteresis and its inverse, and some sufficient conditions for the controllers in both SISO and MIMO systems should be satisfied are also derived respectively. Based on the proposed conditions, influence from hysteresis is rejected, the systems are robustly stable and output tracking performance can be ***, the effectiveness of the proposed method is confirmed by numerical simulations.

In this paper, a decentralized proportional-derivative （PD） controller design for non-uniform motion of a Hamiltonian hybrid system is considered. A Hamiltonian hybrid system with the capability of producing a non-uniform motion is developed. The structural properties of the system are investigated by means of the theory of Hamiltonian systems. A relationship between the parameters of the system and the parameters of the proposed decentralized PD controller is shown to ensure local stability and tracking performance. Simulation results are included to show the obtained non-uniform motion.

目的评价160生物型翻修柄在股骨侧翻修中的短期疗效。方法回顾分析2017年8月至2019年9月在广东省中医院接受春立160型柄股骨侧翻修的患者,评估术前及末次随访的临床及影像学表现,并与同时期行强生Solution柄翻修患者进行比较,术前及末次随访时患者的人工髋关节疗效评分(Harris评分)和牛津大学髋关节评分(OHS评分)采用配对样本t检验,组间比较采用独立样本t检验。结果共有35例患者符合标准、纳入研究并完成随访,其中160型柄组(观察组)患者18名,Solution柄组(对照组)患者17名。与术前相比,观察组患者Harris评分由(34±8)分提高至(72±7)分(t=-13.91,P0.05)。影像学显示假体固定牢靠,两组患者在假体下沉距离和假体松动评级中差异无统计学意义(Z=-0.857、-0.474,均为P>0.05)。结论160生物型翻修柄在髋关节翻修患者的短期随访中表现良好,短期疗效与Solution柄相当,长期疗效有待进一步观察。

A turbine design method based on pressure controlled vortex design （PCVD） is presented to design a small-size turbine stage. Contrary to the conventional controlled vortex design （CVD） method, the main objective of PCVD is to control the axial velocity and radial pressure in the sta- tor rotor gap. Through controlling axial velocity, the PCVD establishes a direct tie to meridional stream surface. Thus stream surface variation is induced, resulting in a large secondary flow vortex covering the full blade passage in the respective stator and rotor. This secondary flow vortex could be dedicated to control the secondary flow mitigation and migration. Through radial pressure, the PCVD is also associated with the macroscopic driving force of fluid motion. So the better benefit of CVD can be achieved. The core concept behind PCVD is to mainly control the spanwise pressure gradient by altering profile loading at various spanwise locations. Therefore not only the local pro- file lift is affected, but also the resulting throat widths, stage reaction degree, and massflow rate are altered or redistributed respectively. With the PCVD method, the global stage efficiency is increased successfully while the mass flow rate keeps constant. Additionally there is no endwall shape optimization, stacking optimization, or pitch/chord variations, concentrating solely on varying blade profile deflections and stagger.
