Control System Design by Multicriteria Selection in Microwave Sintering Processes.

Programa de apoyo I+D+I UPV. 2012.


In this project modeling, monitoring and control processes for microwave sintered materials are developed. This technique is a new application, emerged as an alternative method, has a number of advantages over conventional sintering methods:

  • Rapid distribution of heat evenly.
  • Materials require much less energy to be microwave sintered by conventional methods.
  • The heat diffusion processes are intensified by the use of microwaves.
  • Much higher heating rates are achieved and therefore the sintering time decreases.
  • Greater density in the sintered material and a better distribution of the particles.
  • Improved physical and mechanical properties of the sintered products.

The objectives in the project encompass:

  1. Constructing a prototype microwave cavity incorporating the measuring and actuating elements necessary to automate the process of sintering materials.
  2. Development of nonlinear dynamic mathematical models to describe the behavior of the temperature of the material to be sintered.
  3. Simplification of nonlinear mathematical models to adapt them to the techniques of control systems based on linear algebra, as PID structures and state space.
  4. Design control strategies based on linear optimization enabling management MISO systems robustly.
  5. Design control strategies based on  nonlinear optimization enabling management MISO systems robustly.
  6. Implementation of control algorithms and real tests with the prototype.
  7. Developing a computer application (SCADA) LabView software based enabling monitoring, control and optimization of the entire system sintered autonomously
