Modeling in Time and Frequency Domain

控制系统中的传递函数
控制系统中的传递函数
The transfer function is a mathematical representation that describes the system's output for each possible input in the frequency domain. Consider a ...

电气系统
Electrical networks are first represented by equivalent circuits consisting of three passive linear components: resistors, capacitors, and inductors. ...
机械系统
机械系统
In mechanical systems, springs, and masses are akin to the roles of inductors and capacitors in electrical networks, with the energy-dissipating function ...
机电系统
机电系统
Electromechanical systems represent a unique blend of electrical and mechanical components that integrate seamlessly. A DC motor is a unit that transforms ...
频域中的线性近似
频域中的线性近似
Linear systems exhibit superposition, summing responses to individual inputs, and homogeneity, scaling responses consistently to an input multiplied by a ...
状态空间表示
状态空间表示
The frequency-domain technique, which is commonly used for analyzing and designing feedback control systems, is only suitable for linear, time-invariant ...
将函数传输到状态空间
将函数传输到状态空间
State-space representation is used for simulating physical systems on digital computers. For this, the transfer function must first be converted into ...
状态空间到传递函数
状态空间到传递函数
State-space representation can also be converted into a transfer function in system analysis. The transformation begins with the given state and output ...
时域中的线性近似
时域中的线性近似
Nonlinear systems find a superior modeling in state-space representation. Consider a simple pendulum represented in state-space with the center of mass at ...
