A type-1 system has a zero steady-state tracking error to a ramp input.
举一反三
- If the steady-state error of unity feedback control system to a ramp input is constant, then the system is a type system A: 0 B: I C: II D: III
- The open-loop transfer function of the unity-feedback control system is G(s)=5/(s(s+2)) . When input is the unit-step,the steady-state error is .
- Besides implicit user input, there’s another type of user input which is called explicit user input.<br/>( )
- If an economy is initially in a steady state and it experiences an<br/>increase in its saving rate, then the steady-state capital stock will<br/>____ A: fall. B: stay the same. C: rise. D: rise only if depreciation also rises.
- The country has been in a very poor[input=type:blank,size:4][/input]state ever since the decline of its two major industries. (economic, economy)
