In this paper, a new decoupling control scheme of 2-link industrial manipulator with application of the model following control has been proposed. Compensation torque used for removing interference force between two arms of the manipulator has been designed in feed-forward control loop. Compared with the conventional scheme, the proposed scheme is more simple and realistic to be taken in to practice for general purpose controllers. And, a new design consideration for control gains has also been shown. Moreover, disturbance observer is applied to cope with model error problem in feed-back control loop. Effectiveness of the proposed decoupling control scheme has been confirmed through simulation results.

A simplified hybrid white organic light-emitting diode (WOLED) employing a p-type interlayer isdesigned, simultaneously realizing high efficiency, high color rendering index (CRI), low efficiency roll-off, low voltage and stable color. The device exhibits maximum total efficiencies of 29.8 cd/A and20.9 lm/W, which slightly decrease to 28.6 cd/A and 16.5 lm/W even at a high luminance of 5000 cd/m2. Besides, a slight color-shift and a CRI of 85 at 100 cd/m2 (3.65 V) are obtained. Such superior resultssystematically demonstrate that the use of p-type interlayer is a new way to realize high-performancehybrid WOLEDs.

An efficient single-emitting layer hybrid white organic light-emitting diode (WOLED) was developed,simultaneously fulfilling low efficiency roll-off, stable color and extreme luminance. At the practicalluminance of 1000 cd/m2, a total current efficiency of 42.8 cd/A and power efficiency of 19.2 lm/W areachieved, maintaining as high as 40.5 cd/A and 15.5 lm/W even at 5000 cd/m2. Besides, a slight colorvariation [(0.025, 0.011)] and extreme luminance ( 106 cd/m2) are obtained. The working mechanism isunveiled and it is demonstrated that the triplet-exciton-confining ability of electron transport layersplays a more vital role in device performances, particularly for the lifetime.
