Adaptive LQ control: Conflict between identification and control

Adaptive LQ Control: Conflict Between Identification and Control

We consider one of the fundamental limitations of indirect adaptive control based on the minimization of a quadratic cost criterion and the certainty equivalence principle. We show that the interaction between (closed-loop) identification and optimal control is conflictive in the sense that almost all possible limits of the sequence of parameter estimates induce suboptimal behavior of the adapt...

Hybrid Adaptive LQ Control Of Chemical Reactor

The paper shows one approach to control of a nonlinear process represented by an isothermal continuous stirredtank reactor. The hybrid adaptive controller designed with the use of a polynomial synthesis, LinearQuadratic approach and spectral factorization was used for controlling of the product‘s concentration via change of the volumetric flow rate of the reactant. An adaptivity of the system i...

the relationship between locus of control and iranian efl university students’ beliefs about language learning

this exploratory study aimed to investigate a possible relationship between learners’ beliefs about language learning and one of their personality traits; that is,locus of control (loc). both variables, beliefs and locus of control, are assumed to influence the language learning process. the internal control index (ici) and the beliefs about language learning inventory (balli) were administered...

12 چکیده تفاوت های فردی، به عنوان خصوصیات روانشناختی غالب، باید در سطوح مختلف تدریس و یادگیری زبان کاملاً مورد ملاحظه قرار گیرند. از میان تاثیرگذارترین سازه های روانشناختی که منجر به تفاوت های فردی می شوند، می توان ازهوش چندگانه و منبع کنترل نام برد. هوش چندگانه با جنبه های متفاوتی از هوش سر و کار دارد که ممکن است هر شخص از آن برخوردار باشد. منبع کنترل، به عنوان مفهوم روانشناختی دیگر، به استن...
