This is the second course in control engineering which looks at the state-space representation of systems as well as state-space based control design techniques. The course also introduces basic concepts in System Identification and Nonlinear Control. Traditional continuous-time as well as sampled-data (digital) systems are covered.
|Session||First Sub Session||Credit Points||15 credits (7.5 ECTS credits)|
To extend the work of earlier level courses in control systems to advanced, modern control methods, including transfer function, state vector and artificial-intelligence-based techniques, applicable to the design of both continuous and discrete-time systems.
