Which of the following statements about the time-invariant and time-varying control systems is INCORRECT?
1
The characteristics of time-varying control system change with time and the coefficients of its differential equation are variable coefficient.
2
A time-invariant control system is one in which the parameters of the system are stationary with respect to time during the operation of the system.
3
The characteristics of time-invariant control system do not change with time, and it can be represented by constant coefficient differential equations.
4
A time-varying control system is one in which the parameters of the system are not stationary with respect to time during the operation of the system.
