说明：  近些年我们在嵌入式系统及其应用的科研工作中采用了信息产业中的最新技术，打破了学科之间的界限，感到控制的出路原来很多，尽管处处是挑战。过去我们熟悉的“控制”有很大的局限性.：一是不考虑硬件的限制, 二是不考虑控制器的复杂性及计算能力， 三是 不注重实用性和效益。在微处理器，微传感器和微型执行元件不断推出新产品的形势下,控制的思路与手段正经历着巨大的变化。在经过一番艰苦的实践摸索之后，我们对控制学科的研究和教学有了一些新的认识。本教材就是在我们这些年科研工作的基础上总结出来 的，它还比较粗糙，还需要今后花大力气把它完善与提高。现在拿出来作为试用教材供大家参考，希望能为控制学科教学内容的更新作出我们的一点贡献。
(In recent years we have embedded system and its applications in scientific research work in the information industry using the latest technology, breaking the boundaries between disciplines, are way out of a lot of control, despite a challenge everywhere. The past, we are familiar with the "control" have great limitations.: First, do not consider the hardware limitations, and the other is not considering the complexity of the controller and computing power, and the third is Do not pay attention to the practicality and effectiveness. In microprocessors, micro-sensors and micro-actuator constant introduction of new products to circumstances, ideas and means of control is undergoing tremendous changes. After some difficult in practice to explore, we are subject to the control of research and teaching has some new understanding. The materials in our research work in recent years, summed up the basis of And compare it rough, but also the needs of the future, make great efforts to perfec)
