個人簡介
2013年11月加入上海科技大學(xué)信息科學(xué)與技術(shù)學(xué)院任助理教授。
研究工作
主要從事電能轉(zhuǎn)換系統(tǒng)(power conversion system)和機(jī)電能量轉(zhuǎn)換系統(tǒng)(electromechanical power conversion system)的研究。研究內(nèi)容涵蓋：E類功率放大器的仿真與優(yōu)化；動能收集系統(tǒng)中基本概念的重定義、整體分析理論框架的構(gòu)建、機(jī)電耦合動態(tài)模型的改進(jìn)、能量收集效能的優(yōu)化分析、以及新型能量收集電路的發(fā)明與實(shí)現(xiàn)。其過往最重要的學(xué)術(shù)貢獻(xiàn)在于對阻抗分析方法的理論擴(kuò)展。該理論創(chuàng)新使得傳統(tǒng)上只能用于線性系統(tǒng)的阻抗分析方法在諸如E類功率放大器和壓電能量收集系統(tǒng)等非線性功率轉(zhuǎn)換系統(tǒng)中得到推廣和應(yīng)用。目前研究興趣包括：非線性機(jī)電耦合系統(tǒng)的動力學(xué)建模、動能收集與振動控制、能量轉(zhuǎn)換系統(tǒng)的仿真與優(yōu)化、可再生能源等。
