Dead-zone modification refers to techniques used in control systems to handle non-linearities or saturation effects that occur when the input-output relationship exhibits a 'dead zone' where no output response is observed for certain input levels. This concept is essential in adaptive control strategies, allowing systems to adjust to uncertainties and variations while maintaining stability and performance. By modifying how adaptation laws are applied within the dead zone, control systems can enhance robustness, ensuring that performance is not compromised by these non-linear behaviors.
congrats on reading the definition of dead-zone modification. now let's actually learn it.
