This paper presents optimized fuzzy variable structure control design in a three phase rectifier to correct the power factor. This control strategy combines fuzzy and sliding mode control algorithms. Few fuzzy rules are used for this scheme. The parameters of the fuzzy controller are adjusted by using the VSC for a better response and robustness. To improve the behavior of the system is applied...

Computer systems can be used to control the greenhouse climate in order to improve the culture development and to minimize the production costs. We have a system which allows to acquire the measurements of internal and external temperature and hygrometry, global radiation, and wind velocity. It consists of a heating system, moistening ducts and a static ventilation to control the internal clima...

this paper presents a novel indirect adaptive power system stabilizer (pss) via a developed synergetic control methodology and fuzzy systems. fuzzy system is utilized in an adaptive scheme to estimate the system using a nonlinear model. the synergetic control guarantees robustness of the controller and makes the controller easy to implement because of using a chatter free continuous control law...

The Particle Swarm Optimized (PSO) fuzzy controller has been proposed for indirect vector control of induction motor. In this proposed scheme a Neutral Point Clamped (NPC) multilevel inverter is used and hysteresis current control technique has been adopted for switching the IGBTs. A Mamdani type fuzzy controller is used in place of conventional PI controller. To ensure better performance of fu...

Due to low oxygen solubility and mechanical stirring limitations of a bioreactor, ensuring an adequate supply during recombinant Escherichia coli cultivation is major challenge in process control. Under the light this fact, fuzzy dissolved controller was developed, taking into account decision tree algorithm presented literature, implemented supervision software SUPERSYS_HCDC. The coded MATLAB ...

This paper deals with improvement of superheated steam temperature fuzzy control of high-pressure part in once-through boiler. The improvement of fuzzy control quality is based on optimization of fuzzy controller parameters. The optimization is based on minimization criteria. Optimized fuzzy parameters are function of high pressure steam temperature. More possibilities of optimization are prese...

The paper presents an optimal fuzzy logic control algorithm for vibration mitigation of buildings using magneto-rheological (MR) dampers. MR dampers are semi-active devices and are monitored using external voltage supply. The voltage monitoring of MR damper is accomplished using evolutionary fuzzy system, where the fuzzy system is optimized using evolutionary algorithms (EAs). A micro-genetic a...
