Fuzzy logic PID-control

摘要

A fuzzy control based on the input variables, P-component i.e. control deviation e, the control deviation integral edt (I-component) and the derivative de/dt of the control deviation, and the manipulated variable u, is designed to significantly reduce the time spent on the mathematical inference, and thus the input fuzzy values in the measurement range of the input parameters, and the output fuzzy values in the range of the output manipulated variables, each have two exclusive membership functions which lie symmetrically about the zero point, in the working range, and in which they each have an equal range of values.
