Leg

View this topic in
A leg is a weight bearing and locomotive structure, usually having a columnar shape. During locomotion, legs function as "extensible struts" - the combination of movements at all joints can be modeled as a single, linear element capable of changing length and rotating about an omnidirectional "hip" joint.

  • Modeling and Simulation

    This chapter provides some guidelines for modeling and simulation of the complex dynamics of the modular multilevel converter (MMC). It describes the time¿¿?domain models with different levels of complexity ranging from detailed switching to aggregated averaging and gives useful guidelines for implementation in popular simulation packages. The chapter presents a vectorization simulation technique for N cascaded electrical circuits and their modulators and control. The submodule¿¿?level switched (SLS) model can be used for studies focusing on capacitor balancing methods and for loss evaluation. In the averaged (aggregated) leg¿¿?level averaged (LLA) and arm¿¿?level averaged (ALA) models, only the sum capacitor voltage of each arm is modeled, allowing reduced complexity and shorter simulation times. The submodule¿¿?level averaged (SLA) and submodule¿¿?level switched (SLS) models include each submodule capacitor voltage. Some simulation tools allow vectorization, which simplifies the task of setting up the model, particularly for a large number of submodules per arm N.

  • Biologically Inspired Adaptive Dynamic Walking of a Quadruped Robot

    We have been trying to induce a quadruped robot to walk with medium walking speed on irregular terrain based on biological concepts. We propose the necessary conditions for stable dynamic walking on irregular terrain in general, and we design the mechanical system and the neural system by comparing biological concepts with those necessary conditions described in physical terms. PD-controller at joints constructs the virtual spring-damper system as the visco-elasticity model of a muscle. The neural system model consists of a CPG (central pattern generator), reflexes and responses. A CPG generates rhythmic motion for walking. A CPG receives sensory input and changes the period of its own active phase as responses. The virtual spring- damper system also receives sensory input and outputs torque as reflexes. The states in the virtual spring-damper system are switched based on the phase signal of the CPG. The physical oscillations such as the motion of the virtual spring-damper system of each leg and the rolling motion of the body are mutually entrained with the neural oscillations of CPGs. Consequently, the adaptive walking is generated by the interaction with environment. In this paper, we report our experimental results of dynamic walking on terrains of medium degrees of irregularity in order to verify the effectiveness of the designed neuro-mechanical system.

  • Model Predictive Control of Impedance Source Inverter

    The control strategy of the power converter plays a crucial role in ensuring reliable and efficient operation of renewable based distributed generation (DG) systems. In most applications, proportional-integral (PI) based cascaded control structures have been used to control current, voltage, etc. To eliminate the drawbacks of the cascaded control structure and difficulties of the modulation techniques, this chapter examines the model predictive control (MPC) technique for impedance source - Z-source (ZS) and quasi-Z-source (qZS) - three-leg, four-leg, and multiphase inverters. Then, it presents ZS/qZS three-phase three-leg, four-leg, and multiphase (five-phase) inverter topologies, along with a description of the topology, model, and switching schemes for control. After that, the MPC algorithm for ZS/qZS three-phase, three-leg, four-leg, and multiphase (five-phase) inverters are presented. Finally, to prove the addressed MPC strategy, a performance investigation has been carried out with qZS four-leg inverter and simulation results are presented to demonstrate the capabilities of the MPC.

  • Coordination of Leg Movement in Walking Animals

    When a robot has to move in a locally uncertain environment, propulsion by means of walking legs is advantageous compared to a wheel driven system. However, the control of walking legs is more complicated. The question of how the movement of the different legs is coordinated will be investigated here. Three different solutions which have been developed during natural evolution will be compared. These are the walking systems of an insect, of a crustacea, and of a mammal. The results show that coordinating mechanisms differ considerably in these animals.

  • Adaptive leg placement strategies in the fruit fly set an example for six-legged walking systems

    Poster. Leg placement of the fruit fly Drosophila melanogaster was studied under various visual conditions while walking on a square-wave like linear array of narrow "stepping stones". Three-dimensional high speed video analysis revealed elaborate and error tolerant trajectories of the different legs which depend only to a minor extent on visual influences. Flies do not endeavor to place their legs always on the top surfaces of the treads but equally often cling to the edges or to the side surfaces of the stepping stones. A successful fly-like walking robot would rely on visual influences only for far-field orientation but would exploit a rich mechanosensation at its lower extremities and the ability to attach its legs to various surfaces. Technical solutions for these requirements are currently investigated using a single-leg test stand and a six-legged robot

  • Voltage-Fed Z-Source/Quasi-Z-Source Inverters

    This chapter discusses the voltage-fed Z-source/quasi-Z-source inverters, including their configurations, working principles, voltage and current stresses, and a comparison with their Z-source counterpart. There are several types of voltage-fed ZSI/qZSI, but they have the same principle of operation, in that the shoot-through behavior between power devices of one phase leg is utilized to achieve a voltage boost in single-stage power conversion. The chapter investigates the voltage-fed qZSI with continuous input current as an example to illustrate the principle of ZSI/qZSI in terms of the steady-state model, small-signal dynamic model, and also some simulation results. Parameter scanning of the Bode diagram can be used to optimize the parameter design of a given system in the frequency domain. Its modeling and operation have been investigated in detail with simulation results, providing the basics for other derived impedance topologies and applications.
