Fastest Method to Determine the Elements of an Array From Look-up Table

Asked 2022-Feb-16 at 08:36

Hope everyone is doing well. I am working on a Quadcopter project right now, and I have designed a Gain Scheduling based Controller.

I am using the roll, pitch, and yaw angles of the quadcopter to determine the operating interval. Let me explain the basic idea:

I divided roll, pitch, and yaw into four operating intervals. They are 0-30 degrees, 30-50 degrees, 50-70 degrees, and 70-90 degrees. Therefore, for the roll control, I have 4 PID Controller gain-sets, for pitch control, 4 PID Controller Gain-sets, and for yaw control 4 PID Controller Gain-sets as well. Each Gain Set contains 3 elements. The method has a simple Look-Up table as such (Each Gain Set is an array of 3, including the Proportional, Integral, and Derivative Gains):

This look-up table is constructed for both roll, pitch and yaw angles separately. And as I mentioned, Gain-sets are arrays of 3 elements.

To find the appropriate Gain Set for roll, pitch, and yaw angles I do not know what kind of method would be fastest to use in C, since I am going to implement this Gain Scheduling method on a microcontroller and this gain scheduling method is going to operate in an interrupt function.

I am afraid that if-else structure would be too slow for my needs and therefore wanted have your opinions on that. Thank you so much in advance.

Here is the snippet of the code I wrote (it only covers the Roll/Phi Control part):

As others have commented, it may be fast enough already. So why bother?

Anyway, in a general case, as Nick ODell noted, your comparison is uselessly complex. Just use one fence per if is enough. Moreover you can use memcpy to make the code shorter and clearer.

I have a problem about implementing recommendation system by using Euclidean Distance.

What I want to do is to list some close games with respect to search criteria by game title and genre.

The issue is that you are using euclidean distance for comparing strings. Consider using Levenshtein distance, or something similar, which is designed for strings. NLTK has a function called edit distance that can do this or you can implement it on your own.

I tested your script, and can see the issue; you're not getting the response you're expecting because the scrape is being blocked by Amazon

Before you scrape a website, you need to check their robots.txt to see if you're allowed to; here is the link to it for Amazon, which as you can see has a lot of Disallows in it

What's actually being returned is a robot challenge (see below), and therefore the following part of your code is returning a NoneType

QUESTION

Subscribe to MQTT topic in SwiftUI iOS application

Asked 2020-Oct-11 at 07:31

I'm writing a small iOS app to send MQTT messages to a broker which is hosted on a Raspberry Pi companion computer on my quadcopter. In the iOS app primary view, the app will connect to MQTT Broker (check), send messages associated with several buttons (check), and monitor various quadcopter telemetries such as mode, distance, and lat/long. The iPhone app will display the drones position and the user's position (check) on a map.

The part I'm having issues with currently is having the app maintain a continuous subscription to a topic and then update several variables in the code. Currently, the code below contains the subscription line and "did receive message" code inside of of a button view which only works momentarily when that button is pressed.

I've tried pasting this code in various places within the content view with no success; admittedly I'm a novice coder and Swift/iOS is very new to me. Ideally, the app would continually monitor certain topics and update several variables to equal the message when certain topics are posted to by the drone.

this is my first answer in StackOverflow and I'm a novice too. I was having the same problem, but I can solve it by declaring the "didConnectAck" for the mqttClient; the subscription remains. Just add the following missing lines to your code:
