Basic system categories below,

Figure 1.1 Model Classifications

control system types: servo vs. regulating/process control

open loop vs. closed loop

disturbances

component variations

system error

analysis vs. design

mechatronics

embedded systems

real-time systems

- Basic control problem types,

Tracking (noisy time variant) - test with ramp and disturbance

temperature control

tension/torque control

position

Timing (confliciting objectives and constraints) - test with step

servo control

crane position control

Human Factors (not exact/does not fit LTI) - fuzzy logic

speed control

diagnostics

Interpolation (MIMO system)

multistage setpoint generation

prediction

Classification (not easily described/understood)

pattern recognition
