Types of Control Systems
Control Systems is classified into the following categories: Linear & Non-Linear Systems Static & Dynamic Time invariant & Time variant Causal & non-Causal Difference between Linear and Non-linear systems Linear Non-Linear The relationship of output with the input is linear . The relationship of output with the input is non-linear. Satisfy Homogeneity & Superposition theorems. Doesn’t satisfy Homogeneity & Superposition Example : Register R= V/I Example: Diode : I = I 0 ( e v/t -1) Difference between Static system and Dynamic system Static systems Dynamic systems At any time output of the systems depends only on the present input of the systems. At any time output of the systems depends only on the present as well as the past input of the systems. Memory less systems Presence of Memory Element Y(t) = f (u(t)) This function is jus
