MPI/CPO Manager is the EicasLab Tool specifically conceived to manage the overall model parameter identification and control parameter optimisation process.
The MPI/CPO Manager tool is available in the MPI/CPO module.
EicasLab offers support to the control designer for carrying out these two important tasks to be addressed during the control algorithm development and managed by the professional MPI/CPO Manager tool available in the MPI/CPO module:
The MPI/CPO module integrates the SIMBUILDER with a suitable configuration interface where the user may:
When enabled, the MPI/CPO Manager tool, created through an Assisted Compiling Process, is integrated inside the SIM tool if the user is working in Modelling and Like Real-Time operative mode and in the RCP Manager tool or Slow Motion tool if the user is working respectively in RCP on field operative sub-mode and Slow Motion operative sub-mode with the goal to manage the overall MPI/CPO process.
Specifically, the MPI/CPO process distinguishes the following three main steps:
In the first phase, a preliminary execution - called initial Base Trial - is performed starting from the initial parameter values provided by the user and a preliminary evaluation of the cost function is made. During the initial Base Trial the trends of the variables selected by the user may be displayed in the classical SIM / RCP Manager / Slow Motion plotting window.
At the end of the execution of the initial Base Trial, the second step, named iterative process, starts. It is the iterative part of the MPI/CPO process and in such a phase the parameter values are changed in order to reduce the cost function value, updated at any iteration, until the minimum has been reached, with the requested accuracy. During the iterative process the MPI/CPO Manager GUI gets opened on the screen allowing the user to control the overall iterative process.
The MPI/CPO Manager GUI includes:
When the iterative process is completed the third phase, named final Base Trial, starts. Once achieved the minimum value of the cost function, the final Base Trial is executed with the related parameter values obtained from the previous iterative process. The results are graphically displayed again in the SIM, RCP Manager, Slow Motion GUI for showing a comparison with respect to the ones obtained in the initial Base Trial.
Both in the initial and final Base Trials, SIM, RCP Manager, Slow Motion GUI plots the dynamic behaviour of the variables selected for plotting in order to immediately show the benefits obtained with the MPI/CPO algorithm.
