This paper addresses the synthesis of a predictive controller for a nonlinear process based on a fuzzy model of the Takagi–Sugeno (T–S) type, resulting in a stable closed-loop control system. Conditions are given that guarantee closed-loop robust asymptotic stability for open-loop bounded-input–boundedoutput (BIBO) stable processes with an additive 1-norm bounded model uncertainty. The idea is ...

A review of the experimental evidence shows that passivitybased control of saturated induction motors does not provide superior performance over input–ouput linearization. Higher tracking errors can be observed and traced to the open-loop nature of the flux controller. In contrast, input–output linearization controllers achieve close tracking of flux, speed, and position references for the most...

Recently, neural-network-based adaptive control technique has attracted increasing attentions, because it has provided an efficient and effective way in the control of complex nonlinear or ill-defined systems (Duarte-Mermoud et al., 2005; Hsu et al., 2006; Lin and Hsu, 2003; Lin et al., 1999; Peng et al. 2004). The key elements of this success are the approximation capabilities of the neural ne...

Gas-phase olefin polymerization fluidized-bed reactors are complex processes that are characterized by large time constants and slow transitions. Optimal grade changes can be computed off-line on the basis of a detailed process model and applied to the process in an open-loop mode. However, the presence of uncertainties in the form of process-model mismatch and disturbances make this approach c...

conclusions according to the findings of the current study, both open-loop and closed-loop neuromuscular control mechanisms altered in patients with cai. methods it was a case-control study. twenty-two subjects with unilateral cai and 22 healthy subjects stood on a force plate and initiated gait with maximal velocity under 2 conditions: i) planned (initiated gait after hearing the “all set” sig...

Abstract. The magnitude of wake interactions between individual wind turbines depends on the atmospheric stability. We investigate strategies for loss mitigation through use closed-loop steering using large eddy simulations diurnal cycle, in which variations surface heat flux time modify stability, speed and direction, shear, turbulence, other boundary layer (ABL) flow features. control methodo...

In this paper, control of a non-isothermal continuous stirred tank reactor in which two parallel autocatalytic reactions take place has been addressed. The reactor shows chaotic behavior for a certain set of reactor parameters. In order to control the product concentration, an optimal state feedback controller has been designed. Since concentrations of reactor species are ...

We describe a multi-loop robotic control architecture that for the fine-motion control required for object tracking uses two different loops that depend on entirely different approaches for visual servoing. One tracking loop uses fast blob analysis of the camera images for servo control. The other tracking loop, which is more robust but slower, uses model-based line matchings for a more robust ...

Dear Editor, This letter proposes a robust control strategy for the autonomous landing of quadrotor on moving target. Specifically, force command that consists cascade dynamics estimator and an optimal guaranteed cost law is exploited position-loop tracking. Then, orientation constraint torque employed attitude-loop tracking such refrains from flipping during operation. Stability analysis indic...

Deciding whether an open source software (OSS) meets the required standards for adoption in terms of quality, maturity, activity of development and user support is not a straightforward process. It involves analysing various sources of information, including the project’s source code repositories, communication channels, and bug tracking systems. OSSMETER extends state-of-the-art techniques in ...
