摘要: Walking motions of biped robots have features humanoid and intelligent. Generally, when we human are walking, may control the walking using qualitative instructions, such as linguistic ”slow” or ”fast,” ”forward” ”backward,” ”big step” ”small step”. This motivates us to design a fuzzy controller for robots. Furthermore, improve robustness system, framework gait based on predictable type-2 logic (T2FLC) is proposed ensure dynamic balance under condition complex process noises measurement noises. Different with existing controllers robots, state estimator square root unscented Kalman filter (SRUKF) incorporated in strategy. Using estimated states inputs, T2FLC can predictably adjust posture trunk timely properly whole legged system. Simulation results presented verify effectiveness method.
