Field Application of Microcomputer Controllers

  • W. F. Stoecker
  • P. A. Stoecker


Chapters 1 through 17 have provided a foundation for the understanding and design of microcomputer-based control systems. The final chapter in this book addresses considerations in the field application of microcomputer controllers to thermal and mechanical systems. The chapter opens with a review of the linear proportional-integral (PI) control laws previously discussed in Chapters 16 and 17 and a discussion of their limitations. PI control algorithms suitable for field application are then described in Secs. 18-3 and 18-4.
