## What is the limitation of phase plane analysis?

Disadvantage of Phase Plane Method: graphical study of higher-order is computationally and geometrically complex.

**What are limit cycles in control system?**

A limit cycle is the stability boundary for linear and non-linear control systems. Hamiltonian mechanics and power flow control are employed to demonstrate this property of limit cycles. The presentation begins with the concept of linear limit cycles which is extended to non-linear limit cycles.

### What are the two types of limit cycles?

Stable, unstable and semi-stable limit cycles.

### How do you determine the stability of a limit cycle?

The stability of a limit cycle is determined by its char- acteristic multipliers. The concepts are illustrated us- ing a coupled tank system with on/off valve switching. Hybrid systems are characterized by interactions between continuous (smooth) dynamics and discrete events.

**Do unstable spirals have attractors?**

The attractor is a spiral if it has complex eigenvalues. The system is unstable because the real portion of the complex eigenvalues is positive.

#### How many types of limit cycles are there?

#### Which is types of limit cycle oscillations?

This type of instability usually results in an oscillatory periodic o/p called a limit cycle. There are basically two types limit cycles. 1] Granular. 2] Overflow.

## What is meant by phase plane analysis?

The phase plane method refers to graphically determining the existence of limit cycles in the solutions of the differential equation. With enough of these arrows in place the system behaviour over the regions of plane in analysis can be visualized and limit cycles can be easily identified.

## Is a saddle point an attractor?

Definition: A saddle point is a point that behaves as an attractor for some trajectories and a repellor for others. If one eigenvalue was greater than one and the other less than one then the origin would be a saddle point.
