Structural dynamics and control:

Structural control is reducing unwanted vibrations in structures caused due to various loads; in case of buildings and bridges it could be seismic or wind loads; for naval structures it could be wave load for aircrafts it is flow induced vibrations. In our team we look at passive; active and semi-active methods to reduce structural vibrations. Methods and algorithms developed are applied to reduce vibrations in buildings, bridges, vehicles and helicopters. Focus is also on developing models for application of system and control theory in biological systems, autonomous vehicles and morphing structures.

Fig:1

Biological systems and morphing structures are systems with distributed properties, governed by partial differential equation (PDE). A few members of the lab are focuing on designing controllers for systems driven by PDEs. Uncertainty in parameters and in loading form a special focus.

Design and analysis of energy harvesters:

Fig: 2

Energy harvesting is a technique through which electrical energy is scavenged from ambient resources, like fluid flow, unwanted vibrations of vehicles and structures, etc.

In our team, we design harvesters that exploit principles of linear and nonlinear dynamics. Analysis into dynamics of array of linear harvesters and their interaction in electro-magneto-mechanical fields is the current focus on linear harvesters. Undertanding and exploiting large orbit periodic motion and Chaotic dynamics under multiphysics environment forms the focus of nonlinear harvesters. Harvesters are designed based on both peizoelectric, electromagnetic and hybrid transductions.

Reduced order modelling of large scale dynamical systems:

Mathematical models are used to simulate, and sometimes control, the behavior of large scale dynamical systems like long span flexible bridges, turbine blades, etc. The increasing need for accuracy has led to the development of highly complex models. However, in the presence of limited computational, accuracy, and storage capabilities, model reduction (system approximation) is often necessary. Approximation of Large-Scale Dynamical Systems provides a comprehensive picture of model reduction, combining system theory with numerical linear algebra and computational considerations. It addresses the issue of model reduction and the resulting trade-offs between accuracy and complexity. Special attention is given to numerical aspects, simulation questions, and practical applications.

Currently, the team is working towards developing reduced order models for turbine blades and blisks using sophisticated analytical techniques.

Smart structures and morphing aircrafts:

Fig: 4

The term "smart structures" is commonly used for structures which have the ability to adapt to environmental conditions according to the design requirements. As a rule, the adjustments are designed and performed in order to increase the efficiency or safety of the structure. Combining "smart structures" with the "sophistication" achieved in materials science, information technology, measurement science, sensors, actuators, signal processing, nanotechnology, cybernetics, artificial intelligence, and biomimetics, one can talk about Smart Intelligent Structures. In other words, structures which are able to sense their environment, self-diagnose their condition and adapt in such a way so as to make the design more useful and efficient.

Morphing technology on aircrafts has found increased interest over the last decade because it is likely to enhance performance and efficiency over a wider range of flight conditions. The key technologies in morphing aircrafts include adaptive structures, deformable smart skin, driving actuators, flight dynamics and flight control. Among them, the deformable smart skin and light-weight driving actuators have been the main obstacles to the real-world implementation of the morphing aircraft. The difficulties in the smart skin rest on the contradiction between its ability to resist aerodynamic load in the normal direction and the in-plane flexibility for morphing functions. This contradiction cannot be solved by using sophisticated properties of the skin materials. It can only be solved by new skin structures, which give anisotropic stiffness for bending and in-plane deformation. In this article two skin structures for morphing aircrafts, the wavy skin structure and the honeycomb skin structure, are introduced. The actuators for morphing aircrafts are required to have large stroke, large output force, good compactness, and good controllability. In this article, piezoelectric-hydraulic actuators are introduced.

Reduced order modelling of large scale dynamical systems:

OGY control technique is used for control of the chaotic map. It is a discrete control algorithm, perturbing a system at a discrete point of time. We are implementing the OGY algorithm for any general dynamical system that shows chaotic behavior e.g. Duffing oscillator. The first nonlinear analysis was done to find out the chaotic range of the system with varying parameters (perturbing parameter for OGY). Then an algorithm is implemented to find out fixed points or periodic orbit from given dynamical data points. To find out Jacobian of the map, created from continuous dynamics by sampling data points in a stroboscopic manner, near fix point another numerical algorithm is developed using the least square method. And finally, OGY control is applied to stabilize dynamics. All these algorithms are verified numerically.
