Study Notes
State-Space Modeling
- Utilizes matrices and vectors to represent system parameters and variables, providing a structured mathematical framework.
- Primarily offers insight into complicated, large-scale systems and their dynamic behaviors.
- The state vector encapsulates all necessary information about the system's current status, summarizing its past behaviors.
- The state derivative vector, often referred to as the "state rate," represents the time rate of change of the state vector.
- The dimension of the state model reflects the number of states in the system, essentially indicating the level of complexity and behavior that can be described.
- Primary motivation for using state-space modeling lies in its ability to handle multi-input and multi-output (MIMO) systems, offering a comprehensive view of interactions among variables.
- The output vector in state-space modeling indicates the system's observable outputs, derived from the state vector and external inputs.
- The 'Next state' vector predicts the future state based on the current state and inputs, crucial for system evolution analysis.
- The state of a dynamic system is defined as the set of values that describe its condition at a specific time, governing the system's future behavior if inputs are known.
Transfer Function Modeling
- Provides knowledge about the system's response to inputs in the frequency domain, focusing on stability and performance characteristics.
- It represents the relationship between the input and output through a rational function, allowing for easier analysis of linear time-invariant (LTI) systems.
