Obtaining the faster response with regard to sensitive devices is a critical need in many industrial plants. Regulator can be used in some sensitive systems such as robots, radars, and speed control system (Cruz), which also we need fast response in them. Because of this property in this paper, we suggest new fuzzy logic controller with two inputs contain error and its change. In order to show the generalized model simplicity of the proposed approach, a fuzzy logic controller (FLC) is designed in Matlab/Simulink environment. Then, we used regression analysis for implementation of designed fuzzy controller in practice. The fuzzy regression control is a functional technique to evaluate the process in which the average has a trend and the data represents a linguistic or approximate value. A voltage regulator is designed to automatically maintain a constant voltage level. The simulation results obtained by FLC are also compared with PID and Predictive controllers and prove the ability of proposed FLC. This approach has fast response and focuses on the fuzzy rule base construction.
