【摘要】 基于DSP微处理器,采用自适应模糊控制实现变频恒压供水。根据供水系统水压波动对动态性能的要求,通过分析常规控制器的特点,设计了一维模糊插值器,实时调整模糊控制器比例因子h的取值,使h在动态调节初期取值较大,稳态时较小,以快速消除水压波动对供水系统的影响。该方法提高了系统的稳态精度,加快了系统的响应时间,增强了系统的抗扰能力。更多还原

【Abstract】 The authors report on work in which adaptive fuzzy control in water supply system is proposed based on DSP and the technology of variable frequency. Analyzing the character of general fuzzy controller,we designed a one dimensional fuzzy interplator to regulate the gain h in realtime.By which the gain h will be high when the system starts, low when the system is stable,and high again to cancel interruption when the system is disturbed. The steady state errors are reduced to very small values and the system responds more quickly and become stronger.更多还原
