基于模型的嵌入式PID控制器设计

Model-based embedded PID controller design

在嵌入式控制系统中,PID控制器应用广泛。鉴于实时性和同步性的要求,传统的PID控制器通常采用手工编程来实现。该种实现方式,费时费力,可靠性低,后期的验证测试过程繁杂。为解决该方法不足,本文研究了基于模型的高安全性应用程序开发环境-SCADE,按照SCADE的软件程序设计流程,完成了PID控制器的设计、开发与性能测试,并通过代码的效率测试,验证了SCADE进行嵌入式软件开发的优越性。

PID controller is used widely in embedded control system. Due to the requirement of real-time and synchronism, the traditional PID controller is usually designed by manual code, not only wastes time and energy, but also causes the low reliability and the following inefficient verification. In order to resolve the shortage and seek a more effective way, this paper first researches the model-based Safety-Critical Application Development Environment-SCADE, then accomplishes the design and simulation of PID controller based on SCADE design procedure, and validates the advantages of embedded software design programs on SCADE by the efficiency test of the generated code.
