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.

  • Software Lemmings

    According to the author, software developers, in their search for the Holy Grail, are convinced that they are doing something meaningful. Like lemmings, they tend to follow the leader, without ever asking ourselves if they want to go where the leader is taking them. This chapter presents the lemming paths explored by the author and provides an idea of their popularity, goals, risks and payoffs. It explores the terms structured programming, structured analysis and structured design. Object-oriented programming is based on very sound principles of quality programming discovered 20 to 30 years ago: data abstraction, information hiding, encapsulation, inheritance, and so on. The process-maturity path is only the first leg of a very long journey on the path to quality software. The chapter also talks about the C language, software prototyping, CASE tools, and COTS software.

  • 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.

  • 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

  • OPTIMIZED PWM APPROACH

    This chapter presents some techniques for optimization of the pulse width modulation (PWM) approach considering the fact that the number of pole voltages is higher than the number of voltages demanded by the load, and then there is a degree of freedom to be explored. It shows an optimized PWM strategy for converters with two and three legs, respectively. A PWM approach is presented with both analog and digital implementations, and finally the influence of the parameter is addressed for the quality of the waveform generated as well as for the losses of the converter. The chapter outlines space vector modulation for a three-phase converter. It presents the carrier- based PWM (CPWM) for both a three-leg converter feeding a two-phase symmetrical machine and a four-leg converter supplying a three-phase four-wire load. The CPWM is also employed in non-conventional converters, such as split- wound coupled inductors, Z-source converter, and open-end winding motor.

  • Topology of a Neutral Leg

    This chapter contains sections titled: Introduction Split DC Link Conventional Neutral Leg Independently-Controlled Neutral Leg Summary

  • Applications in Photovoltaic Power Systems

    Z-source/quasi-Z-source inverters (ZSI/qZSI) have attracted considerable attention in photovoltaic (PV) power generation applications because of the single-stage power conversion, no dead time between switches of one bridge leg, and the ability to handle wide dc voltage variation from the PV. This chapter discusses this application, including the typical configurations, parameter design, maximum power point tracking (MPPT), and system control methods, as well as some examples. Separate PV power source is an array composed of identical PV panels in parallel and series. The inverter output power is controlled by the MPPT algorithm. A closed-loop control method was addressed for the three-phase qZSI PV system, which could also be extended to other ZSI/qZSI PV systems. Example simulation results were illustrated for the three configurations. The wide DC voltage handling ability of the ZSI/qZSI in single-stage power conversion provided a wide-ranging investigation into current and future PV applications.
