The effect of intelligent semi-active thermal exchange-fuzzy controller in structural rehabilitation by attenuating seismic responses of structural systems is investigated. In the suggested control system, MR dampers and sensors are employed as a semi-active controller. Resultant control forces of MR damper are administrated by providing external voltage supply, during the earthquakes and high ...

Bus rapid transit (BRT) is one of most effective methods to optimize urban traffic. Transit signal priority (TSP) is very important to increase the efficiency of BRT. TSP provides priority signals for public transport vehicles based on the advanced inspection and communication system. In this paper, TSP control system is designed with wireless sensor networks, which can support real-time inform...

For indirect adaptive fuzzy ∞ H tracking control (AFHC) of perturbed uncertain nonlinear systems, slidingmode control (SMC) compensation usually has to be applied to ensure stability and ∞ H robustness of the closed-loop system. We prove that indirect AFHC without SMC compensation is sufficient to guarantee stable ∞ H tracking under given initial conditions and parameter constraints. The contro...

Traffic flow systems are nonlinear and uncertain, so it is very difficult to find their optimal points. In traditional traffic control systems, the traffic lights of crossings change in a fixed time period that is not optimal. On the other hand, most proposed systems are sufficiently capable of coping with the uncertainties of traffic flow. To solve this problem, there is a need to develop expe...

The paper presents a fuzzy control based on parallel distributed fuzzy controllers for a heat exchanger. Each subcontroller is LQR designed and provides local optimal solutions. First, a Takagi-Sugeno fuzzy model is employed to represent a system. The stability of the system with the proposed fuzzy controllers is discussed. The simulation results are compared with classical PID control and illu...

By integrating the stabilizability condition, the orthogonal-functions approach (OFA) and the hybrid Taguchi-genetic algorithm (HTGA), an integrative computational method is presented in this paper to design the stable and quadratic-optimal static output feedback parallel-distributed-compensation (PDC) controller such that (i) the TakagiSugeno (TS) fuzzy-model-based control system can be stabil...

The precious irrigation is great significance for arid and semiarid area. According to the special environment of greenhouse, a fuzzy control algorithm was proposed to make an optimal irrigation strategy based on the actual measured soil humidity during the whole plant growth process. The fuzzy control system had two inputs (soil humidity error and its rate) and one output (water level differen...
