# Questions tagged [systems-engineering]

Systems Engineering is a multidisciplinary field that combines lifecycle planning and risk analysis with core features of other engineering disciplines. It includes understanding physical systems, organizational planning, computer modeling, and information management. It is also commonly used to describe a position in information technology which involves managing multiple technology stacks and overseeing computer networks.

### Problem finding value of the gain such that the closed loop is stable

I have the following transfer function: $G(s)=\frac{-s^3 +s}{s^4+3s^3+2s^2}$ and this is a transfer function of a plant with two poles in the origin. So I want to desing a controller with two poles ...
