LabView implements most of the mentioned algorithms, some come with tutorials and toolkits, some are white papers, others are programs offered from third parties. Delight yourself with a "Labview <algorithm>" search on your favorite web browser. Note: <algorithm> is generic, insert PID, FUZZY, GENETIC and etc
In the desin of complex control systems with high reliability indices on the spec, such as a nuclear energy powered submarine, safety is integrated across the board on all phases. However, some of the basic design functions stay from time to time with the team of engineers who focus more on the crude functionality of the various processes.
@snandu13 "Is the logic built in Fuzzy logic only in Software? I donot know how Fuzzy Logic is built into the controllers."
You can implement any form of logic in either software or hardware -- a software implementation is more versatile with regard to changing it -- and it can be a lot easier to capture your "intent" -- but a hardware implementation will always be much faster (orders of magnitude in many cases) and consume much less power...
@Clive Maxfield- Ok, I think that I am starting to understand this a little bit better. Add me to the list of people asking you for more book references on this. Thanks again for another great lecture.
@KevinJam: "Saftey system as in the safety Instrumented systems to implement safety functions on the Basic process controll loop is normally handled as an independent network to avoid potentially common cause failure."

yeah, I know how to see exactly how many points I have for each track, but like I said, I have 22 points for the first track, and I thought I watched everyday. Is there anyway to see the point breakout per lecture instead of per track?
@clia "@Clive Maxfield - So, is GA something that would be most apt to use when not looking for immediate responses?"
I would say you've nailed it -- you use GA to quickly find an optimal solution amongst an almost infinite solution space -- once you have that solution you run with it.
But they you have th efact that in a complex system the problem itself (for example the surrounding environment) may change over time ... in which cas eyo umay wish to have an adaptive system -- and the way th esystem adapts may be based on GA techniques...
@jrjohns: "Given the non-deterministic nature of GA, it seems unlikely that you will see GA used in critical safety systems (or is there a way to get this type of system approved?)"
At the moment I think GA is more of interest in coming up with optimal solutions to a system -- by which I mean more in setting the system up -- as opposed to being used "on th efly" while the system is running
the best approach is to understand the nature of the type of process being controlled / its inherent behaviour before choosing a control strategy...it is possible you may well compose a combination of stragy approaches
Max: Actually, the notion of model based design is not only inherant to Model Predictive Control, but has been with P, PD, PID since before the II world War in practical applications such as syc machine control and rocket launching and navigational control.
@MaxianLab: an event occurs at a point in time and then is over, but a state is a condition of the system which can change the interpretation of incoming events. For example, a switch closure would be an event and might or might not cause a state change. Initialization might be a state in which such switch closures are ignored, while normal operation might be a state where the switch closures are detected and responded to somehow (perhaps with a change to yet another state).
You haven't really programmed a computer until you have set at a console with 24 switches to set the 0s and 1s for a word and pushed another switch to enter each word in memory before running the program.
The streaming audio player will appear on this web page when the show starts at 2pm eastern today. Note however that some companies block live audio streams. If when the show starts you don't hear any audio, try refreshing your browser.
A slew of announcements about new materials and design concepts for transportation have come out of several trade shows focusing on plastics, aircraft interiors, heavy trucks, and automotive engineering. A few more announcements have come independent of any trade shows, maybe just because it's spring.
Samsung's Galaxy line of smartphones used to fare quite well in the repairability department, but last year's flagship S5 model took a tumble, scoring a meh-inducing 5/10. Will the newly redesigned S6 lead us back into star-studded territory, or will we sink further into the depths of a repairability black hole?
Focus on Fundamentals consists of 45-minute on-line classes that cover a host of technologies. You learn without leaving the comfort of your desk. All classes are taught by subject-matter experts and all are archived. So if you can't attend live, attend at your convenience.
