stabilisator

A stabilizer, or stabilisator in some languages, is a device or substance designed to maintain or improve the stability of a system by counteracting disturbances or preventing degradation.

Stabilizers are used across many domains, including mechanical, electrical, chemical, and optical applications, where small changes can affect performance or safety.

In mechanical and aerospace contexts, stabilizers include fins, gyroscopes, and tail surfaces. Horizontal and vertical stabilizers on aircraft help control pitch and yaw, while ship stabilizers counter roll in rough seas.

Electrical stabilizers regulate voltages and currents to keep outputs within safe ranges. Voltage regulators, uninterruptible power supplies, and grid-stabilization equipment all serve this purpose in power systems and consumer electronics.

Chemical stabilizers are additives that slow degradation or separation. Examples include antioxidants and light stabilizers for polymers, as well as emulsifiers and thickeners that maintain mixtures in foods and cosmetics.

In photography and film, stabilizers such as gimbals and steadicams counteract camera shake, enabling smoother motion footage even during movement.

Overall, stabilizers play a role in safety, reliability, and quality by maintaining conditions within desired limits across diverse industries.
