Examples.HydraulicActuator

HydraulicActuator(; name)

A simple hydraulic actuator model with first-order dynamics.

Variables

• u(t): Control signal input
• y(t): Actuator force output
• x(t): Internal state variable

Description

Implements a first-order hydraulic actuator system with the following dynamics: dx/dt = -100.0 * x + 3000.0 * u y = 1.0 * x

The actuator responds to control signals with time constant 1/100 = 0.01 seconds and steady-state gain of 3000.0/100.0 = 30.0.

Usage

PrimitiveComponents.Examples.HydraulicActuator()

Connectors

• u - This connector represents a real signal as an input to a component (RealInput)
• y - This connector represents a real signal as an output from a component (RealOutput)

Variables

Behavior

\[ \begin{align} \frac{\mathrm{d} x\left( t \right)}{\mathrm{d}t} &= 3000 u\left( t \right) - 100 x\left( t \right) \\ y\left( t \right) &= x\left( t \right) \end{align} \]
