Finding average speed or rate

The only bke here is that we will include the filter dynamics as part of our "plant" bike computer 0.5 second recording we will consider our input to be duty cycle a percentage rather than input voltage. From inspection, the steady-state speed reached by the motor is approximately RPM. Recall that bike computer 0.5 second recording time constant defines the time it takes a process to achieve Therefore, we can estimate the time constant based on the time it takes the motor speed to reach RPM.

Since this appears to occur at 1. Therefore, our blackbox model for the motor is the following. recordig

In this section, we will initially design our PI controller algebraically. That is, we will choose the control gains and to place the closed-loop poles in some desired locations.

Therefore, we must first determine the closed-loop transfer function for the system as defined above. By inspection, we see that the closed-loop system is second-order with a zero. The system does not match the canonical form shown below because of the presence of the zero.

0.5 recording computer bike second

Despite the presence of the zero, we will initially treat our system as if it did have a canonical form. Therefore, our initial design will not reflect the true behavior of our closed-loop system with zero not to mention the uncertainty in the plant model.

Garmin edge 1030 gps cycling computer head unit these limitations, this design will provide a good starting point and will prove qualitatively helpful to us in the tuning of our controller. Matching the denominator recorving our closed-loop 05 function to the canonical form above, we get the following relationships between control gains and recordimg closed-loop pole locations as indicated by, etc.

We can then choose our control gains in an attempt to achieve closed-loop pole locations that satisfy biike original system requirements on settling time, peak time, and maximum overshoot.

In this process we will use the following expressions, which again assume a canonical second-order underdamped system which we don't have. Based on the given requirements and assumed relationships shown bike computer 0.5 second recording, we can determine the desired poles locations that in turn determine our choice of control gains and. In order to satisfy our settling time requirement, we place the following constraint on. Now examining bike computer 0.5 second recording peak time requirement, we determine a constraint on.

And finally, our maximum percent overshoot requirement places a constraint on. If we choose our gains to meet the three above constraints, our closed-loop system will not be guaranteed to meet the associated requirements because our system is not canonical it has bike computer 0.5 second recording zero and because our actual physical plant won't match our recordihg model.

That being said, the above relationships are still useful in bike computer gps reviews guiding the sefond of the control gains, as we will vomputer demonstrate. To help visualize the above requirements, we will map them to the complex s-plane as shown below. Specifically, corresponds to the real part of our poles, corresponds to the imaginary part of our poles, and maps to bike computer 0.5 second recording angle via the relation.

Therefore, we need. The shaded region corresponds to the pole locations that satisfy all three requirements.

0.5 bike recording computer second

Based on these requirements, we can choose the closed-loop poles to equal. We could also choose the bike computer 0.5 second recording to meet the requirements with greater recordibg, the only drawback is that making the system "faster" smaller settling time and smaller peak time tends to come at the cost of increased control effort, something we will discuss when we implement our controller.

Now looking back at our original closed-loop transfer function, we can pick our control gains and to achieve the chosen closed-loop pole locations, where equals 5 and equals We will develop and implement our control algorithm within Simulink.

We can begin with the model that we used previously for bike computer 0.5 second recording a model for our plant. Starting from this model, we can add a PI compensator as shown below, where the reference speed command bike computer 0.5 second recording be recorving step of magnitude RPM chosen to be less than the motor's maximum speed, RPM in this case. This reference then subtracts the plant's output, which in this case is the filtered estimate of the motor's speed.

The output of this summing junction, the measured speed error, is then garmin gps cycling hike into the control algorithm. The controller in this case has two terms, the P term which is proportional to the error via the gainand the I term which is proportional to the integral of the error via the gain.

The sum of these two terms is the control input to the plant.

The control input is specifically the duty cycle of the PWM signal applied to the motor. The name of this block is a bit of a misnomer since it generates a PWM signal which is still a digital output. If we employed an H-bridge, we could also drive the gps mobile holder for bike backwards recordinv a "negative" control inputbut in this activity we only command the motor to spin in one bike computer 0.5 second recording.

You can create the model yourself, or download it here. Once we have created this model, it can then be run to bike computer 0.5 second recording the performance of the controller we just designed. Just out of interest, let's first run our model with only a P controller.

That is, set and let. Under these conditions, our closed-loop system generates the following response to a step reference of RPM.

second recording computer 0.5 bike

Since recorsing didn't perform our controller design for a P controller, we don't know exactly what to expect in terms of the transient response.

However, it is interesting to inspect the steady-state response. Here we see that the steady-state speed settles somewhere below 60 RPM which is quite different than the Best triathlon bike gps reference that was commanded.

The presence of such a level of steady-state error, however, is not surprising since our system is type 0 under P control. Let us now add the integral term we designed earlier. The system response that is produced for this PI controller is shown below. Examining the resulting steady-state response, the motor's speed seems to settle out near the commanded reference cmputer RPM. This is expected since the addition of the integral term to our controller increased the system's type to 1. The transient response, however, isn't exactly what we designed for.

Specifically, we designed our controller to place the system's closed loop poles at. If these poles belonged to a canonical second-order system, we would then expect the system's step response to have the following characteristics:. Inspection of bike computer 0.5 second recording recorded motor speed demonstrates that the system is more oscillatory larger overshoot bike computer 0.5 second recording settling time than designed for.
