Control System Programs (details) | Prime ENG 16 KB / 36 KB |
Ten programs that could potentially be useful for anyone in a control systems class. The first program takes as input the system matrix (a) and the input matrix (b) to find the controllability matrix. With it there is another function that will check if the controllability matrix found is controllable or not. The next program takes the system matrix (a) and the output matrix (c) as inputs to find the observability matrix. Along with it is another function to check if the observability matrix is observable. The third function uses Ackermann's Formula to find the feedback constants. It takes as input the system matrix (a), the input matrix (b), and the desired characteristic equation coefficients. The other programs convert the system from a statespace model to a transfer function, convert the system from a transfer function to statespace form, create the Routh table from the characteristic equation, find the Static Error Constants (Kp - position, Kv - velocity, Ka - acceleration) and also their respective steady state errors (essp - step, essv - ramp, essa - parabola), solve for all possible input combinations to solve for a second order system, graph the step response of the transfer function, and find the step response characteristics of the step response graph. | |

Frozen Orbit Design (details) | Prime ENG 302 KB / 15 KB |
Determines the mean orbital eccentricity required for a frozen orbit. The user provides the mean semimajor axis and inclination and the program calculates the eccentricity using Brent’s method to solve the single constraining nonlinear equation. A frozen orbit is characterized by the absence of long-term changes in orbital eccentricity and argument of perigee. This type of orbit maintains almost constant altitude over any particular point on a planet’s surface. The design of frozen orbits involves selecting the correct value of orbital eccentricity and argument of perigee, for a given semimajor axis and orbital inclination, which satisfies a system of nonlinear perturbation equations. | |

Nodal Period of an Earth Satellite (details) | Prime ENG 238 KB / 43 KB |
Calculates the nodal period of a satellite using a numerical integration technique. The algorithm first uses the RKF78 method to propagate the first-order perturbed equations of satellite motion forward in time to bracket a "nodal objective function". Once a bracket is found, the algorithm then uses Brent's root-finding method to find the time at which the objective function is zero to within a user-defined tolerance. While looking for the root the software also uses the RKF78 method to propagate the satellite's orbit subject to the main oblateness gravity perturbation of the Earth. | |

Noise Figure and Noise Voltage (details) | Prime ENG 4 KB / 3 KB |
Given system temperature (in Kelvins), the first program calculates the noise figure (in Decibels), which describes the noise performance of an amplifier. The noise figure is described as the difference between the noise output of an actual receiver to an ideal, noiseless receiver. A noiseless receiver is said to have a resistor operating at room temperature, 290 K (about 16.85°C or 62.33°F). The lower the noise figure, the better. Given the noise bandwidth (in Hertz) and the resistance (in Ω), the second program calculates the open-circuit voltage (in RMS volts). | |

Shadow Conditions of Earth Satellites - Kozai Orbit (details) | Prime ENG 369 KB / 85 KB |
Accurate predictions of shadow conditions for any type of satellite orbit can be determined by using a combination of one-dimensional minimization and root finding. The algorithm used here searches for minimum values of the angle between the shadow axis and the satellite’s position vector as a function of time. If this angle lies within the penumbra angle, the algorithm uses Brent's root-finding method to look backward and forward relative to this minimum time to find entrance and exit conditions. This method can also be used to determine entrance and exit relative to the umbra, penumbra and cylindrical shadows. | |
