#### 6. Specific goals for the course

**a.** The student will…

- Mathematical Solutions: solve applied math problems involving linear ordinary differential equations, integration by parts, perform partial fraction expansion; use the Laplace Transform to solve differential equations; Laplace Transform look-up tables, solve inverse Laplace Transform problems.
- Model-based Control: use MATLAB, Simulink, and/or visual basic simulator to computationally model process control, to make simple mathematic calculations, to solve differential equations, to take the Laplace Transform of a function, to plot curves representing response of a control loop, and to implement other simulation-based actions covered in class.
- Basic Process Control Concepts and Calculations: draw and use block diagrams of open and closed-loop transfer functions for control problems; identify control system instrumentation (sensors, transmitters, transducer, final control elements); use process control techniques to address safety concerns; use process control vocabulary appropriately; choose a control strategy for a process; formulate control objectives; identify, formulate and solve linear chemical process dynamics problems; formulate and solve an approximate linear model to a nonlinear process; analyze the stability of a dynamic system.
- PID Control Concepts: tune a P, PI, or PID controller using control theory; choose the appropriate control action (P, PI, PID) for a particular process,
- Other topics: develop process models of non-steady-state process dynamics; Identify appropriate loop pairings for multivariable control; identify and implement feedforward and feedback control strategies; implement single-variable controllers (temperature, pressure, concentration, flow, level); and identify advanced control strategies and apply them in appropriate situations (cascade, ratio, pH).
