in this paper, the consequences of well-known characteristics of near-fault ground motions, forward directivity and fling step, on the seismic response control is investigated. an integrated fuzzy rule-based control strategy for building structures incorporated with semi active friction damping system with amplifying braces (fdsab) is developed. the membership functions and fuzzy rules of fuzzy...

The objective of this study is minimizing the frequency deviation due to load variations and fluctuations renewable energy resources. In paper, a new type-2 fuzzy control (T2FLC) approach presented for (LFC) in power systems with multi-areas, demand response (DR), battery storage system (BESS), wind farms. BESS used reduce deviations caused by energy, DR utilized increase network stability fast...

The principle and implementation procedure of genetic algorithms were introduced and were applied to optnmze the parameters of fuzzy controller which control the superheat of evaporator in refrigeration system. Simulation results of performance of optimized fuzzy control rules, comparing with the primary rules, were obtained.

Quad rotor is a renowned underactuated Unmanned Aerial Vehicle (UAV) with widespread military and civilian applications. Despite its simple structure, the vehicle suffers from inherent instability. Therefore, control designers always face formidable challenge in stabilization and control goal. In this paper fuzzy membership functions of the quad rotor’s fuzzy controllers are optimized using nat...

The remarkable properties of sliding mode control (SMC)—such as robustness, accuracy, and ease implementation—have contributed to its wide adoption by the community. To accurately compensate for parametric uncertainties, switching part SMC controller should have gains that are sufficiently large deal with but small minimize chattering phenomena. Hence, proper adjustment is crucial ensure accura...

Abstract: One of control methods for underactuated manipulators is known as a switching control which selects a partiallystable controller using a prespecified switching rule. A switching computed torque control with a fuzzy energy region method was proposed. In this approach, some partly stable controllers are designed by the computed torque method, and a switching rule is based on fuzzy energ...

Numerical Control, NC, machine tool feed servo systems are time-varying, but with the poor anti-interference of conventional PID control it is difficult to achieve satisfactory setting effect. Thus this paper puts forward an online adaptive fuzzy PID setting strategy. Further, in order to improve the control performance of fuzzy PID controllers, we use a genetic algorithm to set the initial PID...
