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 relationship between initial length and tension of the cable is developed based on the analytical expression of catenary, so the forces applied to the end nodes can be solved exactly and efficiently.The simplified dynamic model of cabin-cable system for large spherical radio telescope is established with Newton-Euler formulation.Aiming at the characteristics of nonlinearity,slow time-variant and multivariable coupling,a novel bifuzzy control method with proportional-integral-tuning unit,which optimizes the control rules by adjusting factors,is utilized to realize the trajectory tracking of the feed.The dynamic system is simulated with expected signal input via the bi-fuzzy controller.The results show satisfactory tracking performance and higher trajectory tracking accuracy of the feed cable-supporting system.
