### Linearization of Non Linear State Space Model

The typical steps followed to linearise the system $\dot{x} = f(x, u)$ is to split the state variable into two parts; a steady part (operating point) and a small-signal part. This can be done with ...

### What is the current component at the input of dc-dc converters?

Generally in DC-DC circuit models, the converter load is modeled as a current source (i2) with a resistance in parallel. This is to generalize the model as much as possible and to take into account ...

### Why is it necessary to know a state of a system?

If the system has memory, you need to know what state the memory is in. For example: a system with a low pass filter of a resistor and a capacitor will respond differently if the capacitor is fully ...

### State Space Clock Model & Control

This is more of an extended comment than an answer. The system may be inherently discrete-time. It may not make sense to find the continuous time plant model, as it may not exist. I am not familiar ...

### Relationship between eigen values and state feedback

My question is that even if we have control over eigen values of this new vector how does that help us control the system i.e. to bring our system to our desired state? If you consider your system as ...

### control systems - state space representation using transfer functions

There are several ways to convert a transfer function into a state space representation. They lead to apparently different results, but retain the same essential information. Possible representations:...

### Why is it necessary to know a state of a system?

1) when you consider a state feedback controller 2) when linear system theory can not be applied ( nonlinear systems) 3)when you don‘t have a sensor for the state you are interested in (estimators) ...

### Averaging matrix is not invertible in state space averaging

I am going to just assume that this is a "mathematical problem" rather than an engineering problem. As @Sparky256 and @Dorian have mentioned, the circuit topology is questionable and not practical. I ...
