3. MODELLING & SIMULATION
Modelling is the process of representing the behaviour of a real system by a collection of mathematical equations and logic.
Physical-mathematical description of a technical component, subassembly or a complex system.
Simulation is the process of solving the same model on computer.
Calculation of the behavior of a system model in dependence on time, and the state of a system and environment. The simulation provides projections about the behavior of the real system with the aid of a model, which can be executed in a computer.
Simulation process has the three basic steps:
Initialization
Iteration
Termination

4. AUTOMATIC CONTROL
System control is achieved by sensors, actuators and embedded microcontrollers.
A system in which, the output has an effect upon the input quantity, in such a manner to maintain the desired output value is automatic control system.

5. Example - for a box-shaped luggage to maximise volume:
OPTIMIZATION
In Mechatronics, optimization is primarily used to establish the optimal system configuration. It solves the problem of distributing limiting resources throughout a system such that the pre-specified aspects of its behavior is satisfied.
Here, resources are referred to as design variables, aspects of system behaviour as objectives, and system governing relationships (equations and logic) as constraints.
Example - for a box-shaped luggage to maximise volume:
Design variables : L (length), W (width), H (height)
Objective : Maximise V = V(L,W,H)
Constraints : System relationship V = LHW

6. Key elements of Mechatronic systems can be classified under following categories
1. Information systems
2. Mechanical systems
3. Electrical systems
4. Computer system
5. Sensors and actuators
6. Real time interfacing

7. Integration of Components (Hardware Integration)
Embedded with sensors, actuators and microcomputers
Designing the mechatronics system which integrating the sensors, actuators and computers into the mechanical process and can be arranged at several places.
Integration of Information Processing (Software Integration)
Embedded with advanced control functions
Besides a Feed forward and feed back control, an additional influence may take place through the process knowledge and corresponding online information processing. This means processing of available signals at higher levels using fault diagnosis and optimization

8. Classification of Mechatronics system

9. Phases of Mechatronics design process
Modeling : Systems are represented by a suitable model for evaluating the
behavior characteristics using simulation methods.
Prototyping : Sensors and actuators are interfaced with i/p and o/p signals with the
trial models, resulting in partial mathematical and real models. Here
real part provides real-time analysis and mathematical part provides
simulated time-based response. We can synchronized to understand
and validate the design
Deployment : Associated with the final product, embedded software deployment and
lifecycle.

10. Steps involved in modeling and simulation
Need : Adaptive market research and knowledge must be
accumulator to achieve a clear picture of what the
customer wants.
Feasibility : Examine the commercial as well as technical aspects
of the proposed product such as Warranty and future
maintenance cost which will influence the profitability.
Specifications : It encompasses the weight, payload and interfaces,etc.
Conceptual design : Generate six possible solution.
Embodiment & : Once optimal solution has been identified, we move to
Optimization detailed design phase and the production of
manufacturing drawings

11. Integrated Design Approach

12. MCT consists of several interconnected subsystem and components
TYPES OF DESIGN [
Design for strength or stiffness
Design for reliability
Design for maintainability - Features such as repair on replacement
Design for manufacture - Concerned for Automatic assembly. Here the machine
capability must be taken into account for the
rationalisation of component, fixture & fitting between
between similar product & process.
Traditional Approach Mechatronics Approach
Original and operating characteristics will changes due to the actual loading and dynamic interactions.
Perfect impedance matching of the two designed system is quite difficult
System is reliable due the integrated system design.

13. Traditional Approach
Mechatronic Approach
Bulky system
Complex mechanism
Rigid heavy structures
Manual control
Non adjustable movement cycle
Accuracy is less
Compact
Simplified mechanism
Lighter structures
Automatic and programmable control
Programmable movements.
Good accuracy due to feedback
