In this paper, researching and producing on current waveform control system of inverter carbon dioxide welding machine is given. the overall plan, the design of hardware structure, the programming and debugging of software is described in detail. the bang - bang and alterable structure discrete pid synthetic control algorithm are used to modulate the width of pwm signal in real time, to acquire the fiat character by driving and controlling the opening and shutting time of igbt, the technology of " double impulse " is adopted to realize electric current waveform control
本文介紹了逆變波形控制co _ 2焊機控制系統的研製，詳細闡述了總體方案的制定、硬體研製及軟體的編寫與調試，採用變結構、離散型pid + bang - bang復合控制演算法、實時調節輸出pwm信號的脈沖寬度，驅動控制用於逆變的大功率開關管igbt的開通與關斷時間，獲得逆變焊機平外特性。 -
Familiar on - line monitoring device for overvoltage just monitor inner overvoltage, but the device introduced in the paper can monitor lighting impulse overvoltage and inner overvoltage in lokv distribution system. with the characteristics of overvoltage in the lokv distribution network, the principle of on - line device for overvoltage monitoring is introduced. divider, coaxial line, trigger, signal processing, data acquisition, acquisition control and waveform analysis software is included in the device. when the device operate in the system, overvoltage is transferred to coaxial line by divider. if the
通常的過電壓監測裝置只能監測一些內過電壓，而本裝置設計目的是能夠同時監測雷電過電壓和內過電壓。本文結合10kv配電系統的過電壓特點，提出了10kv配電網過電壓的在線監測裝置的基本原理，並研製成功了實用的在線監測裝置。該裝置包括分壓器、同軸電纜、觸發電路、信號處理、數據採集、控制和分析軟體。 -
In waveform design aspect the impulse response elimination method is presented to detect and discriminate the targets. in the signature waveform detection aspect the target ' s late - time response is adopted as the signature waveform, then the adaptive beam formation arithmetic is used to detect this signature waveform
在發射波形設計中提出了沖擊響應消去法，設計與目標匹配的發射波形來檢測和識別目標；在特徵波形檢測中提出用目標沖擊響應的晚期響應作為目標的特徵波形，再利用自適應波束形成的演算法來檢測待測目標的特徵波形。 -
