What is Fuzzy PID controller?

Fuzzy Pid Controller is a proportional derivative-derivative controller that uses fuzzy logical software principles as a form of errors in industrial systems. PID controllers are widely used in automation to modify the valves and other process controls based on the accumulation of errors over time. Where the Fuzzy PID controller differs from the standard PID controller, it is in its ability to provide more accurate results in non -linear situations. Fuzzy systems are based on the type of programming logic that attempts to deal with gray areas of uncertainty in processes more successful than standard controls. Typical PID controllers will have a response to this variability at the set points in a process that can be compared in some way with the digital view method of viewing the process by doing so. Fuzzy PID regulator, on the other hand, calculates the deviation along the analogue range, where the optimum value and increasingly non -optimal value, but no predefined point, inwhich is always acting.

Fuzzy PID controller and standard PID controller use historical values ​​to calculate future responses. In fact, the letters in PID mean that P is present, even for past mistakes and D as the future error states. Fuzzy systems try to map errors in terms of persistence and assign them to different sets of membership for different ranges of logical conditions. This allows Fuzzy PID to set the speed change speed under control. This rate of change is based on inference rules where data and error states indicate the most correct procedure.

One foil with the Fuzzy PID controller is that it can reach conclusions that are contradictory and no steps. This requires the process of solving conflicts in a code that is commonly referred to as a defusion in Fuzzy Systems. Defuzzling is done by providing to determinePID parameters greater weight than others to tilt the balance in a certain direction of action, and this is an analogous modified profit in the standard PID controller.

In the case of standard variations, Fuzzy PID controller and standard PID controller can regulate the control system in the same way. This does not indicate that they are the same control systems or that the benefits of fuzzy control have been refuted. It simply means that the situation is easily solved by any basic control system. PID standard controllers can be considered a subgroup of Fuzzy PID controller, which has a more robust and capable ability to handle unpredictable deviation. In situations where standard PID controllers fail, a well -designed fuzzy PID controller will work better.

The benefits offered by Fuzzy PID controller include that it can provide different levels of response levels to non -linear variations in the system, and at the same time a standard PID controller can work in the system where the variation is predictable. Fuzzy PID driver can also maintain StabiLighter system. It can be weighed on the types of responses as well as the profit setting on a standard PID controlled system.
