Q. Explain Time-invariant versus time-varying systems?
When the parameters of a control systemare stationary with respect to time during the operation of the system, the system is known as a time-invariant system. Even though a time-varying system without nonlinearity is still a linear system, the analysis and design of such a class of systems are generally much more complex than that of linear time-invariant systems.
