主要針對中、大容量供水系統中，由於供水管網鋪設復雜、彎管多、控制對象具有高階、滯后、耦合、非線性及參數時變的特點，難以利用有效的解析式數學模型進行閉環控制，以及多臺水泵並聯運行時，水泵電機由變頻電源供電向工頻電源供電切換過程中產生的過電壓過電流沖擊這兩個難題，提出了可調整因子fuzzy - pid控制演算法及利用鎖相環控制實現水泵電機由變頻電源向工頻電源的同頻同相平滑切換。The third chapter first describes the operating mechanism of private funds, then focuses on practical methods to control the risks involved. comparatively speaking, china ' s private funds do n ' t have as many investment tools as their foreign counterparts and they mainly operate in the secondary stock market. as a result, the risks private funds confront are tremendous : private funds in china have no legal status, which indicates that the fund contract ca n ' t get proper legal protection ; the stock market has been far from perfect so that private funds have inadequate instruments to avoid risks ; the listed companies participating in private funds are vulnerable to risks ; private funds investors also confront the risks of unexpected policy change
