# Dynamic vs Algebraic
|
|
- Dynamic system has "memory", output depends on present and past
|
|
- Includes diff and/or integral operators with initial conditions
|
|
- Cap and or inducer
|
|
- Algebraic
|
|
- No calculus operators
|
|
- Output depends only on input
|
|
|
|
# Time Invariant vs Time-Varying
|
|
|
|
# Continuous vs Discrete time
|
|
|
|
# Linear vs Non-Linear
|
|
|
|
# Deterministic vs Stochastic
|
|
- Deterministic
|
|
- Output fully determined by parameter inputs
|
|
- Stochastic
|
|
- Include randomness
|
|
- Noise/Disturbance
|
|
- Same inputs can lead to different outputs
|
|
|
|
# Lumped vs Distributed parameters
|
|
- Lumped
|
|
- Only one independent variable (time $t$)
|
|
- Typical for electrical systems
|
|
- $x(t)$
|
|
- Ordinary differential equations
|
|
- Distributed
|
|
- Several independent variables
|
|
- time, pressure, temperature
|
|
- Typical for chemical processes and process control
|
|
-$x(t, P, T)$
|
|
- Differential partial equations
|
|
|
|
# Causal vs Non-Causal
|
|
- Causal
|
|
- Output depends only on current and past values
|
|
- Non-Causal
|
|
- Output depends on future inputs
|
|
|
|
# SISO vs MIMO
|
|
- Single Input/Single Output
|
|
- Multiple Input/Multiple Output |
