  tracking performance
Master-slaver dual-leg coordination control was proposed for the biped robot with heterogeneous legs (BRHL), in order to reduce gait planning and to get a good tracking performance.
      
The feedback controller improves system tracking performance and suppresses load and mechanical disturbance while the feedforward controller compensates phase hysteresis introduced by feedback control.
      
Prediction is also implemented in the algorithm to locate the target in order to keep it stationary in the center of the image, resolve events of occlusion or masking, and increase normal tracking performance.
      
Simulations are designed to test the tracking performance of DIMM-MSJPDA algorithm.
      
The results show that the use of DIMM-MSJPDA algorithm enables the distributed multisensor system to track multiplied maneuvering targets and its tracking performance is much better than that of IMMJPDA algorithm.

Five young male subjects wearing an anti-G suit were exposed to +G stress at four seatback angles and were tested for tracking performance on a human centrifuge of six meter radius. Some physical parameters, tracking error, output signal of side-arm controller and physiological parameters such as ECG, upper arm blood pressure and respiration were recorded. Method of complex analysis and system indentitication were used for data processing.It showed that subject's mean tracking error and psycho-physiological...

Five young male subjects wearing an anti-G suit were exposed to +G stress at four seatback angles and were tested for tracking performance on a human centrifuge of six meter radius. Some physical parameters, tracking error, output signal of side-arm controller and physiological parameters such as ECG, upper arm blood pressure and respiration were recorded. Method of complex analysis and system indentitication were used for data processing.It showed that subject's mean tracking error and psycho-physiological load increase with increase of G value and decrease of seat-back angles. Subject's tracking performance was improved by inflation of a-nti-G suit at G levels 0.3G lower than G levels at which peripheral vision loss occured. In comparing human operating dynamic parameters such as steady gain, effective delay time and frequency of tracking motion at 15 and 60 seatback angle. It was found that tracking performance was better at 60 seatback angle. Method for evaluation of human working ability and cause of change in human operator tracking performance under +G stress, were also analysed and discussed.

This paper describes the design of a BTT missile autopilot by means of the classical control theory, and the guidance logic using the proportional guidance law without any constraint in the maximum roll angle of the missile. Full trajectory numerical simulations are computed and analyzed in the following different conditions of combination: wichout constraint in maximum roll angle or with constraint in the angle between -90 to +90 degree; with or without a yaw channal; with or without the consideration of the...

This paper describes the design of a BTT missile autopilot by means of the classical control theory, and the guidance logic using the proportional guidance law without any constraint in the maximum roll angle of the missile. Full trajectory numerical simulations are computed and analyzed in the following different conditions of combination: wichout constraint in maximum roll angle or with constraint in the angle between -90 to +90 degree; with or without a yaw channal; with or without the consideration of the dynamics of sensors in the control system. The Tesults show that the designed guidance system, guidance logic and the autopilot are correct, reasonable and significant in practical engineering applications. They also verify that the BTT missiles have the characters of large attacking range, good tracking performance, and hitting the target stably when it's in larger maneuvering.
