Double pendulum with a single PID

Asked 2020-Sep-05 at 18:10

I'm trying to understand how to use Drake to control a simple Double Pendulum using a PID controller.

Following the example at this link, I created a similar program but I only wanted to try to use 1 PID on the lower joint and see what the system did. (I am aware it is impossible to get to a stable state in this manner)

Instead of constructing PID controller with a scalar Kp, Kd, Ki gain, you should use a size 2 vector as the gain. Since you only want to control the lower joint, then only the entry corresponding to the lower joint is non-zero in the gain matrix.

I think you can change your code to

QUESTION

microPython attributeError in __init__

Asked 2018-Nov-23 at 18:02

EDIT: Thanks to the age old tradition of unplugging and plugging everything back in I got it to work; I reflashed the WiPy module and reinstalled the Pymakr plugin.

I am currently in the process of writing a PID-controller for micropython (we have to make a linefollower). I have implemented the PID algorithm in microPython as a class.

I will be using the WiPy module from Pycom to control my linefollower.

For now the actual program doesn't do much, I just wanted to test if the program was reasonably fast, as such I have some random numbers for the input and the K-values and the output function is just left empty.

However whenever I try to run a little test script where I create the object and calculate the PID a 100 times, I get an attributeError in the init of the PID-class. This is the method that gives me trouble:

You're receiving this error because you are attempting to assign an attribute which hasn't been declared and I assume you are using python 2's classic class style. Add a definition for last_calculate_time in your PID class such as last_calculate_time = None and then it should work as expected.

A more suitable approach would be passing object as an argument to your class definition as below, causing it to be treated as a New Style Class:
