Parkinson’s disease (PD) is a degenerative disease that affects the motor system, which may cause slowness of the speech and the movements, and the anomaly of writing abilities due to tremor. PD diagnosis by Deep Learning approach has become an important worldwide medical issue through the last years. It is obvious that these patients due to their physical conditions are not suitable for every kind of PD diagnosis test. One of the non-invasive PD identification methods is the handwriting test, which is utilized in hospitals since many years ago. In this work we propose Convolutional Neural Network (CNN) based Deep Learning system to learn features from Handwriting drawing spirals which are drawn by People with Parkinson; also, we evaluated the performance of our deep learning model by K-Fold cross validation and Leave-one-out cross validation (LOOCV) techniques. Moreover, we introduce a dataset with a novel test which is called Dynamic Spiral Test (DST) along with traditional Static Spiral Test (SST) for PD recognition. We used both dynamic features and visual attributes of spirals. The proposed approach was reached to 88% accuracy value. The analysis of handwritten drawing tests proves that it is useful to combine SST and DST tests for automatic PD identification.

Unstable processes are frequently encountered in industrial applications. Proportional-Integral-Derivative (PID) controllers are the most widespread used controllers for controlling unstable processes. However, it has been shown that PID controllers perform unsatisfactorily for controlling unstable processes. Therefore, this study reports on the use of I-PD controllers for improving closed loop performances of unstable processes. Optimal and analytical tuning rules have been derived to calculate tuning parameters of the I-PD controller. Simulation results, giving comparisons of some existing PID and I-PD design methods to control open loop unstable processes, have been supplied to illustrate superior closed loop performance of the proposed optimal and analytical I-PD design approach.

This paper proposes a new design of fractional order adaptive PI (PIα) controller for a class of first order plus time delay (FOPTD) plants. An offline tuning method is achieved to fix the fractional order α, to satisfy gain and phase margin specifications. Then, an adaptive control is used to adjust online the basic parameters Kp and Ki. The robustness of the proposed scheme is ensured by the property of the well-known Bode’s ideal transfer function. The resulting adaptive control ensures more robustness against gain variations, due to the use of fractional operators. Simulation results confirm much the effectiveness of the proposed tuning scheme.

Digital implementations of chaotic systems are periodic and they are degraded versions of the original chaotic system. Hence, all digital pseudo random number generators based on chaotic systems inherently contain several weaknesses. These weaknesses are eliminated using various methods like cascading multiple chaotic systems and applying small perturbation to the calculations. Another method is switching parameter values of a dynamical system to obtain different chaotic behaviors. There is an example of such a method in the literature which demonstrates the switching between continuous-time ODE based Chen-like and Lorenz-like systems. In this study, a similar approach is followed and four different discrete-time Chebyshev maps are utilized for pseudo random number generation by switching a single parameter value. Just like in the other study about parameter switching method, the resulting attractor is a combination of the individual attractors of the switched systems. A direct approach is used for bit extraction and the resulting random sequences successfully pass the NIST SP 800-22 randomness tests.

In this study, we have proposed an unconventional UAV design. We aimed heavy lifting in an efficient way, without using complicated swashplate mechanism. Helicopter consist of two large propellers to carry the main payload, two small propellers to stabilize the roll attitude, and two servo motors to control the yaw axis. Large propellers will be more efficient than the small propellers owing to their greater disk area. For this reason, main lifting will be achieved by two large propellers. Conventional quadcopters have "PNPN" (P: Clockwise, N: Counterclockwise) propeller arrangement. However, the system we proposed has "PPNN" propeller arrangement to compensate the reaction torques of equally sized propeller pairs which are placed at opposite sides. However, quadcopters with "PPNN" propeller arrangement loses controllability upon hovering. Therefore, controllability is satisfied by adding servo motors to small propellers for tilting. We have derived the nonlinear dynamic equations, linearized the system around the equilibrium point and performed controllability analysis. An autopilot and controller is designed and, the system is simulated with realistic parameters. System performance is shown to be satisfactory.

This paper proposes a tuning technique of proportional-integral (PI) parameters using genetic algorithm (GA) to improve the performance of the speed control system of permanent magnet synchronous motor (PMSM). PI controller is the most common control method used in both industrial and special applications. The adjustment of the optimal values of PI controller is an important issue for the performance of PMSM. GA based PI controller and the effects of tuning a closed loop control system are discussed in this paper. The aim of this study is to compare the conventional PI parameter tuning method with GA optimization tuning method in terms of time to determine the optimal value. The simulation results show that GA based PI (GA-PI) method provides better performance than conventional methods.

In this work we propose a visual servoing strategy on multiple triangles underoing different piecewise rigid motion. Our strategy is to compute first a correction related to each triangle independently using its related interaction matrix. Then, we process an average global correction to correct the camera pose and obtain a view which is as close as possible to the desired visual features. We show that this strategy performs better than a naive one with a single interaction matrix that gathers all the triangles. We use an analytic version of the image moments on 2D triangles and apply the proposed strategy on several triangle poses to show its relevance.

Telemetry tests conducted for a missile aim to improve ongoing design work in order to better meet the performance requirements. These tests can be performed before/during the qualification stage and the design team can observe the missile’s performance via the data collected in these tests. These data packages are transmitted by wireless (radio frequency-RF) communication to a ground station for post-processing. Considering the importance of telemetry tests in affecting the project’s work in the design phase, it is important to accomplish them by gathering as much data as possible. This study proposes compressing telemetry data before the transmission process in order to reduce the bandwidth requirement. Thus, the study investigates this practice’s effects on the RF communication range and the increase in link margin via link budget calculations. Considering the characteristics of missile telemetry data (rate of change, different frame formats, etc.), synthetic telemetry data were generated in accordance with the real-life data structures, then this data were compressed using lossless data compression methods. While investigating the effects of transmitting a data train of decreased bandwidth on RF communication parameters, link budget analysis was conducted while keeping the unrelated RF parameters such as the type of modulation, transmitter/receiver characteristics, antenna properties constant. Results show that different compression algorithms provide variable amounts of improvement in downsizing the telemetry data; thus helping to increase a telemetry flight tests’ efficiency for missiles.

In this paper, an adaptive controller is proposed for attitude and altitude control of a quadrotor. First, mathematical and dynamic models of a quadrotor are analyzed. Next, PID and LQR controllers are designed separately. This step is followed by application of hyperbolic tangent weight function to increase the overall performance by selecting the proper controller at proper time. Finally, all the three controllers’ performances are observed in Matlab Simulink simulation environment. Simulations show that adaptive controller’s overall performance is remarkably superior to that of a single PID or LQR controller.
