The temperature control method of electrical heating is utilized, which adopts Fuzzy-PID control arithmetic and realizes steady temperature control by controlling the heating power. The Fuzzy-PID control of electrical heating in the calibration system for large diameter heatmeters is simulated in this paper. Its results indicate that the control method, whose control precision is between plusmn0.1degC,...
In single-phase shunt active power filter (SAPF), there are several methods to obtain the best reference control current. The theory of instantaneous reactive power has been successfully used in three-phase symmetrical and asymmetrical power systems, but it is too complicated to apply into single-phase power systems because of complex coordination converting by single-phase to three-phase and then...
For the fuzzy-PID can't cope well with the variable plant including variable parameters and time-delay, an adaptive double-mode fuzzy predictive controller combined with fuzzy control, adaptive control and generalized predictive control is introduced in the paper. The simulations show that this method is feasible and can overcome the uncertain disturbance/noise efficiently. At the same time to reduce...
