Department of Mechanical and Aerospace Engineering
This unit commences with the modelling of various dynamic engineering systems, followed by the analysis of their transient and steady-state responses. More sophisticated analytical methods such as root locus and frequency response will be explored and will build the foundation for controller design in the future. Modelling via state-space methods will also be briefly covered.
At the end of this unit, students are expected to:
- Value the significance and relevance of systems and associated control in engineering
- Formulate linear dynamic mathematical models of various systems (mechanical, electrical, fluid, hydraulic and pneumatic) as well as graphical models (such as block diagrams and signal flow graphs) using time-domain, frequency-domain and state-space techniques together with the unified concept of resistance, capacitance and inertia/inductance
- Calculate the response of systems as a function of time using classical differential equation solution, Laplace transforms and state-space method
- Analyse the stability and dynamic performance of a system using root locus and Bode plot methods, and calculate system parameters to achieve the desired dynamic response
- Recognise the effects of non-linearity in systems and accept the limitations of the use of linear models as approximations
- Formulate solutions using computer-based techniques (such as Matlab)
Continuous assessment: 40%
Final Examination (3 hours): 60%
Students are required to achieve at least 45% in the total continuous assessment component and at least 45% in the final examination component and an overall mark of 50% to achieve a pass grade in the unit. Students failing to achieve this requirement will be given a maximum of 45% in the unit.
3 hours of lectures, 2 hours of tutorials and 6 hours of private study per week plus two 3-hour laboratories during semester.
