数字化电源的特点：1.控制智能化它是以数字信号处理器(DSP)或微控制器(MCU)为核心，将数字电源驱动器及PWM控制器作为控制对象而构成的智能化开关电源系统。传统的由微控制器控制的开关电源，一般只是控制电源的启动和关断，并非真正意义的数字电源。2.数模组件组合优化采用“整合数字电源”(Fusion DIGITAL Power)技术，实现了开关电源中模拟组件与数字组件的优化组合。例如，功率级所用的模拟组件MOSFET驱动器，可以很方便地与数字电源控制器相连并实现各种保护及偏置电源管理，而PWM控制器也属于数控模拟芯片。3.集成度高实现了电源系统单片集成化(Power System on Chip)，将大量的分立式元器件整合到一个芯片或一组芯片中。4.控制精度高能充分发挥数字信号处理器及微控制器的优势，使所设计的数字电源达到高技术指标。例如，其脉宽调制(PWM)分辨力可达150ps(10~12s)的水平，这是传统开关电源所望尘莫及的。数字电源还能实现多相位控制、非线性控制、负载均流以及故障预测等功能，为研制绿色节能型开关电源提供了便利条件。5.模块化程度高数字电源模块化程度高，各模块之间可以方便地实现有机融合，便于构成分布式数字电源系统，提高电源系统的可靠性。

This texts contemporary approach focuses on the concepts of linear control systems, rather than computational mechanics. Straightforward coverage includes an integrated treatment of both classical and modern control system methods. The text emphasizes design with discussions of problem formulation, design criteria, physical constraints, several design methods, and implementation of compensators.Discussions of topics not found in other texts--such as pole placement, model matching and robust tracking--add to the texts cutting-edge presentation. Students will appreciate the applications and discussions of practical aspects, including the leading problem in developing block diagrams, noise, disturbances, and plant perturbations. State feedback and state estimators are designed using state variable equations and transfer functions, offering a comparison of the two approaches. The incorporation of MATLAB throughout the text helps students to avoid time-consuming computation and concentrate on control system design and analysis
