Improving System Performance Fundamentally, we wish to improve the performance of our systems in terms of the principal control systems design criteria: transient response, steady-state error, and stability.

Improving System Performance Fundamentally, we wish to improve the performance of our systems in terms of the principal control systems design criteria: transient response, steady-state error, and stability. We saw in the Steady-State Error unit that the addition of integration (1 / s trans. function) into the forward path can reduce finite SS error to zero.

We saw in the Steady-State Error unit that the addition of integration (1 / s trans. function) into the forward path can reduce finite SS error to zero. Here we discuss in more detail how to achieve this.

However, while we are happy with the damping ratio ζ and % OS at A we would prefer the reduced settling time at B .
