摘要:本設(shè)計(jì)基于AT89S52 單片機(jī)，以他勵(lì)直流電動(dòng)機(jī)的數(shù)學(xué)模型和無靜差直流調(diào)速理論為理論依據(jù)，完成了無轉(zhuǎn)速傳感器的直流調(diào)速系統(tǒng)的初步設(shè)計(jì)。實(shí)現(xiàn)了直流調(diào)速系統(tǒng)的數(shù)字化和無速度傳感器化，在滿足一般工程需要的請情況下，為直流調(diào)速系統(tǒng)節(jié)省了一套測速裝置，既節(jié)省了成本，也提高了系統(tǒng)的穩(wěn)定性。隨著微機(jī)技術(shù)和電力電子技術(shù)的發(fā)展，高速微處理器和高速開關(guān)管應(yīng)用于直流電動(dòng)機(jī)調(diào)速成為可能，打破了以往直流電動(dòng)機(jī)串電阻調(diào)速和一些低效率調(diào)速的歷史。本文用直流電動(dòng)機(jī)的數(shù)學(xué)模型來估算電機(jī)的轉(zhuǎn)速，克服了傳統(tǒng)速度傳感器的抗干擾性不強(qiáng)的缺點(diǎn)。 關(guān)鍵詞 無轉(zhuǎn)速傳感器； 直流調(diào)速系統(tǒng)； 單片機(jī)
Abstract:The design is based on AT89S52 microcontroller, with his excited DC motor mathematical model and no static error DC converter theory as the theoretical basis and completed without speed sensor DC speed control system preliminary design. DC speed control system to achieve digitization and speed sensor technology, to meet the needs of your general engineering case, DC speed control system saves a speed measuring device, saving costs, but also improve the stability of the system. With computer technology and power electronics technology, high-speed microprocessors and high-speed switch for DC motor speed control as possible, breaking the previous series resistance speed DC motor and some inefficient governor's history. In this paper, the DC motor mathematical model to estimate the motor speed to overcome the traditional immunity of the speed sensor is not strong disadvantage Keyword: No Speed Sensor DC Speed Control System SCM |
