UCL Mechanical Engineering
Faculty of Engineering Sciences


MECH202P Control and Instrumentation

To provide students with an understanding of the tools & techniques required to interface between mechanical components and the wider world, involving sensing, actuation (e.g. motors) modelling and control.

Code: MECH202P
Alt Codes: None
Title: Control and Instrumentation
UCL Credits/ECTS: 0.5/7.5
Start: September
End: April
Taught by: Dr. Ryo Torii


ENGS101P Integrated Engineering

Method of Instruction

  • Whole-class lectures will be used to present standard theories of control, dynamics & instrumentation, using examples from a range of industries and research fields to demonstrate their applicability.
  • Students will be challenged to conduct self-led investigation of electrical machines and control in real-world applications.
  • Laboratory sessions will give students hands-on experience with dynamic mechanism and examples of instrumentation and measurement. These will be in small groups of no more than 6 students.
  • Online e-resources will be used to support learning objectives.


The course will have the following assessment components:

  • Examination (2 hours, 50%)
  • Lab participation and coursework (50%)

To pass this course students must:

  • Obtain an overall pass mark of 40% for all sections combined.


 Modelling Dynamic Systems

  • Time-response (“dynamics”) of first- and second-order systems: including examples of electrical filters used to reduce ripple & electrical noise.
  • Ordinary differential equations (ODE), to complement (not duplicate) the Mechanics of Solids and core IEP modelling & analysis syllabus.
  • Mass-spring-damper systems and the concepts of resonance.


Measures of strain (strain gauge), displacement (optical encoder, LVDT, possibly hall-effect sensor), force, velocity, temperature.

Control and Electrical Power

  • Introduction to control. Open- and closed-loop control representation, emphasising open loop = “model-based predictive control”. Examples of regulation, including cruise control (speed), temperature control.
  • Feedback, and the general structure of a control loop.
  • Electric motor types, including impedance.

MECH202P Control and Instrumentation

Intended Learning Outcomes

Following successful completion of this course, students would be able to:

  • Create linear analytical models of dynamic systems and solve them to identify the response of those systems to a range of inputs.
  • Select appropriate sensors which may be required to interface between a mechanical system and its application (e.g. displacement sensor).
  • Identify the important components of a control loop, and choose a general control
  • Analyse a range of electrical power machines and identify their suitability for applications.
