Kontrollálatlanság

Kontrollálatlanság refers to a state in which a person, system, or process cannot be steered or guided toward a desired outcome, even with efforts or available inputs. The term is used across disciplines to describe a deficiency in influence over outcomes or behavior.

In control theory, kontrollálatlanság describes a situation where a system cannot be driven to all possible states by admissible inputs. For a linear time-invariant system described by x' = Ax + Bu, the system is controllable if the controllability matrix has full rank; otherwise it is uncontrollable. When uncontrollable, some modes or states cannot be reached from given initial conditions, which imposes performance limits and may require redesigning the system, adding inputs, or changing the model.

In psychology and social sciences, kontrollálatlanság often refers to perceived or actual lack of control, which can influence motivation, stress, and behavior. Perceived lack of control is linked to phenomena such as learned helplessness and is studied in relation to resilience, coping strategies, and well-being. It can arise from chronic illness, adverse life events, or persistent uncertainty, and it is distinguished from the mere presence of control by the subjective experience of influence.

In technology and societal contexts, kontrollálatlanság can emerge in complex or nonlinear systems due to feedback loops, disturbances, or component failures. It raises safety and reliability concerns in engineering and operations, prompting emphasis on redundancy, fault detection, and robust control methods. The term is also used metaphorically to describe organizations or processes that resist change or external steering.

Related concepts include controllability, the Kalman criterion, perceived control, and learned helplessness.
