电力系统有责任确保充足的电力交付给负载，既可靠地和在经济方面。任何电气系统必须保持所需的经营水平，名义上的频率和电压配置文件的特点。但电力系统跟踪负载的能力是有限的由于物理和技术考虑。因此，电力系统控制要求连续之间保持平衡力量一代和负载的需求。在电力系统的操作过程中由于负载的连续和随机变化影响是电源的质量。负载频率控制器 (LFC) 和自动电压调节器 （AVR） 在维持恒定频率和电压，以保证电力系统的可靠性具有重要作用。为此应用程序使用的固定的增益 PID 控制器不能在不同负荷条件下执行，从而提高穷人的动态特性的大型沉淀时间、 过冲和震荡。在本文中，进化算法(EA) 一样，增强粒子群优化 （EPSO）、 多目标粒子群优化 （粒子） 和随机微粒群算法优化 （SPSO） 提出了克服中标准的粒子群优化算法的早熟收敛问题。这些算法减少暂态振荡，也提高了计算效率。仿真结果表明所设计的控制器适应自己相应的不同荷载作用下并因此提供更好的性能特点，对沉降时间、 振荡和超调量。

在现代化的工业生产设备中，有大量的数字量及模拟量的控制装置，例如电机的起停，电磁阀的开闭，产品的计数， 温度、压力、流量的设定与控制等，工业现场中的这些自动控制问题，若采用可编程序控制器( P C ) 来解决自动控制问题已成为 最有效的工具之一，本文叙述P C 控制系统设计时应该注意的问题。-In modern industrial production equipment, there are a large number of digital and analog control devices, such as motor starting stop, solenoid valve opening and closing, product count, temperature, pressure, flow and control settings such as, industrial site automatic control of these problems, the use of programmable logic controller (PC) to solve the automatic control issue has become one of the most effective tool, this article describes the design of PC control system should pay attention to.

Autonomous indoor mobile robots are gaining increasing popularity for the shared use in military and civil applications. Recently aerial or ground robots of various shapes and sizes have been developed for quick detection and observation of circumstances in calamity environments such as indoor fire spots [1, 2]. In an indoor environment, however, weak reception of GPS signals has posed additional challenges to the operation of the robots. Therefore less expensive self-localization with unaided external sensors is one of the most important problems in popularizing indoor mobile robot products.
