The delay of the sensory-motor feedback loop is a destabilizing factor within the neural control mechanism of quiet standing. The purposes of this study were 1) to experimentally identify the neuromusculoskeletal torque-generation process during standing posture and 2) to investigate the effect of the delay induced by this system on the control mechanism of balance during quiet standing. Ten he...

Control of dynamical systems gets considerably harder with an increasing number of control variables. Especially when the control variables are restricted to integer values, the solution is of combinatorial complexity. An example of such systems are Digital Hydraulic Drives, where several cylinders contribute to the output torque independently. In this work we present an optimal control approac...

The aim of our study was to compare crank torque profile and perceived exertion between the Monark ergometer (818 E) and two outdoor cycling conditions: level ground and uphill road cycling. Seven male cyclists performed seven tests in seated position at different pedaling cadences: (a) in the laboratory at 60, 80, and 100 rpm; (b) on level terrain at 80 and 100 rpm; and (c) on uphill terrain (...

Due to less pollution, silence and high efficiency electric vehicles are fascinating to the citizens widely. There are number of physical and electrical aspects are to be considered during vehicle modeling. When electric vehicle runs on the concrete surface rolling resistance resist the vehicle tire to move fast. On the other hand when the vertical angle of vehicle drive is increased or decreas...

In this paper the performance of three-phase induction motor, fed from SPWM & MSPWM inverters are discussed. Computer simulations are used to compare the performances. The 3 phase induction motor model is simulated with sinusoidal excitation. The line current, output power, and efficiency are compared with the experimental results. The simulated results are very close to the practical values an...

A new indirect stator flux field-oriented output feedback control for Doubly Fed Induction Machine is presented. It assures global exponential torque tracking and stabilization of the stator-side power factor at unity level, provided that electric machine physical constraints are satisfied. Based on the inner torque control system, a speed tracking controller, with load torque compensation is d...

This paper implements and compares Fuzzy-GA Direct Torque Control of AC drive with a fuzzy logic stand alone control architecture model. Fuzzy rules are generated by designers using trial and error method. Genetic Algorithm based fuzzy rules increase effectiveness and feasibility of control system. Direct Torque Control induction motors are characterized by complex, highly non-linear and time v...

Most existing techniques which employ DWT (discrete wavelet transform) to detect servomechanism fault events are based on the analysis of measured motor current signals. However, the outcomes of these techniques tend to be unreliable when the motor suddenly accelerates or generates a very high output torque. Accordingly, to reduce the occurrence of false alarms, this paper develops a fault dete...

In this Paper, an Intelligent Direct Torque Control (DTC) method is proposed for controlling induction motor using Multilevel inverter with space Vector Modulation (SVM).A stage of Artificial Neural Network (ANN) is utilised for predicting the target parameters with the corresponding input parameters change in motor torque and flux. The change in motor torque and flux parameters are extracted f...
