Examples
- This paper focuses on the research of fuzzy control , especially rule self - adjusting fuzzy control method . by theoretic analysis and simulations , the influences of parameters and system performance characteristic of some kinds of rule on - line self - regulating fuzzy control methods are discussed , and a novel real - time self - adjusting fuzzy control method ( vsrsafc ) is proposed from the diagrammatic point of view . in vsrsafc , the slope of the rectifying curve of rule scaling factor a is altered by the fine - tuning and coarse tuning combined mechanism to adjust the fuzzy control rules according to error e and error change ec , which more coincides with characteristic of system response than the conventional self - adjusting method that adjusts rule scaling factor only according to the error e , and has better static and dynamic performances than the latter
其中变斜率规则自调整模糊控制的效果较为明显，它是基于插值的非线性规则自调整模糊控制的引申以及常规全论域规则自调整模糊控制的改进，该方法采用粗、细调结合机制，通过改变规则调整因子的修正曲线斜率，使系统同时根据误差e以及误差变化ec在线调整模糊控制规则，比传统的仅基于系统误差e的自调整方法更符合系统响应特性，可获得更好的动静态控制性能，特别是对于系统参数发生改变、控制参数选取不当等不良状况，控制器仍能较快自调整，具有较强的在线自适应能力。 - A switch ic for analog signal processing is designed and implemented , which can fulfill the functions of sampling , weighting , controlling and summing of high frequency analog signals . the circuit consists of three parts : four channel analog switches , a voltage reference and the control circuitry . each analog switch is comprised of two high - transconductance n - mosfets with high w / l ratio , which realize the fine tuning and coarse tuning of the input signal respectively
