  1. I guess one more question though..the way I determine the best is by just taking the MIN(value1, value2,etc...)   So If I set it to will be the best. Would setting it to 99999 work as well?
  2. .........that's smart... Can't believe I didn't think of that!   Thank you, legend.
  3. Hi guys, I'm using a Schneider Electric M340 PLC, I have a multi-dimensional array: Array[1..10,1..10] of real. To give a little background. Each of those 10 arrays contains 6 parameters for a controller. They're run through a test and the score is recorded in the 7th element. Now my problem is I need to sort those 10 arrays based on that 7th element. More specifically I need to pluck the best two performing ones and write them to a new array set.. I've tried writing my own sorting algorithm although I only manage to take the first, best performing one as opposed to the top two. This of course is programmed in ST. Any advice would be appreciated, Kind regards, Max
  4. Thanks cHud, I'll give that a go!
  5. Hi guys, I'm attempting to implement a fuzzy logic controller from scratch. I plan on using a lookup table to assist with retrieving the membership value. Does anyone know how to implement a lookup table. I know there is a L9P_LKUP block in the LL984 editor..except I'm not sure how to actually enter in the parameters or read from it.   Kind regards, Luchek
  6. Hi guys, I'm in the middle of a little university project, I'm attempting to implement a control system purely based on artificial intelligence. A neural network will be used to map the characteristics of a power plant. A fuzzy logic controller will be used instead of the conventional PID and finally a genetic algorithm will be used to tune the controller while the system is online. This is all simulated of course. Each of those AI's will be developed in Matlab. Only problem with that is, is it outputs the code in C or C++ (From memory). I would have to convert this to structured text (Based on Pascal). So to circumvent this problem I thought I would just directly interface matlab to the PLC (Schneiders M340).  My idea being, all the calculations are done in matlab which are then sent back to the PLC. However this presents me with a new problem of how I would be able to interface matlab to the PLC. If anyone has experience with this sort of connectivity, any advice would be greatly appreciated. Thank you in advance, Luchek
