11.22. Steady-State Errors for Different Types of Systems

The steady-state errors due to different standard input signals and for different types of systems are given in Table 11.2.

Table 11.2. Steady-State Errors for Different Standard Input Signals to Different Types of Systems

System	Unit Step Input	Unit Ramp Input	Unit Parabolic Input
Type0		∞	∞
Type1	0		∞
Type2	0	0
where , ,

As can be observed from Table 11.2, the Type 0 system shows steady state errors ...
