“…Therefore, an observer is proposed to estimate the torque-load based on the d-q axis model, so that it can reduce he chattering phenomenon and improve the speed response of the drive. The estimated load torque is presented in (20),…”

“…This topology is expected to reduce the chattering system and giving a faster speed response and reduce the ripple during the loaded condition. Other researchers also use sliding surface [20], [21], and terminal SMC [22]- [24]. While another strategy is using control law [25]- [27], which introduce the non-linear term by choosing the appropriate law so that it can reduce the chattering problem and reduce the convergence rate.…”

<span lang="EN-US">This <span>paper aims to develop the sliding mode control (SMC) scheme in sensorless permanent magnet synchronous machine (PMSM) drives to replace conventional proportional integral (PI) speed control. The SMC is formulated based on the integral sliding surface of the speed error. And the error is corrected based on the concept of Lyapunov stability. The SMC is designed with the load torque observer so that the disturbance can be estimated as feedback to the controller. The vector control technique which is also known as field-oriented control (FOC) is also used to split the stator current into the magnetic field generating part which is the direct axis and the torque generating part which is the quadrature axis. This can be done by using Park and Clarke transformations. The performance of the proposed SMC is tested under changes in load-torque and without load for different speed commands. The results prove that the SMC produces robust performances under variations of speeds and load disturbances. The effectiveness of the proposed method is verified and simulated by using MATLAB/SIMULINK </span>software.</span>

ÖZETKayan kipli kontrol, uygun şartlar yerine geldiğinde, dış bozucular ve belirsizliklere rağmen istenilen dinamik davranışı sağlayabilen gürbüz bir kontrol yöntemidir. Kayan kipli kontrol yöntemi, uygulama basitliği ve gürbüzlüğünden dolayı, son yıllarda gözde hale gelmiş, çok sayıda kayan kipli kontrol tekniği geliştirilmiş, mühendislik uygulamalarda yerini almıştır. Ancak, açık literatürde bu kontrol tekniklerinin çeşitli gerçek sistemler üzerinde aynı anda uygulandığı kapsamlı bir çalışma bulunmadığı görülmüştür. Bu çalışmada, pratikte kullanılan bazı kayan kipli kontrol teknikleri çeşitli gerçek sistemler üzerinde teorik ve deneysel olarak incelenmiştir. Bu amaçla, tek giriş tek çıkışlı doğru akım motoru tahrikli doğrusal bilyalı kızak sistemi, doğrusal olmayan basit ters sarkaç ve tek giriş çok çıkışlı dolaylı tahrikli doğrusal olmayan arabalı ters sarkaç sistemi olmak üzere üç farklı gerçek sistem kullanılmıştır. Bu sistemlerin kontrolleri, hem teorik hem de deneysel olarak tatmin edici düzeyde gerçekleştirilmiş, elde edilen çok sayıda simülasyon ve deney sonuçları değerlendirilerek karşılaştırmalar yapılmış, çeşitli sonuçlar çıkarılmış, ileriye dönük çalışmalar için önerilerde bulunulmuştur.Anahtar Kelimeler: kayan kipli kontrol, doğrusal olmayan sistem, ters sarkaç, modelleme, simülasyon, deney THEORETICAL AND EXPERIMENTAL INVESTIGATION OF SOME SLIDING MODE CONTROL TECHNIQUES USED IN PRACTICE ABSTRACTSliding mode control is a robust control technique which is able to provide a desired dynamic behaviour in spite of disturbances and uncertainties under matching conditions. In recent years, because of simplicity and robustness, sliding mode control has become popular and various sliding mode control techniques have been developed and taken place in engineering practices. However, it is found that a comprehensive study dealing with the application of these control techniques on various real systems is not available in open literature. In this study, some commonly used sliding mode control techniques are investigated theoretically, and experimentally applying on various real systems. For this purpose, three different types of real systems are used: a single input single output direct current motor driven linear recirculating ball bearing system; a nonlinear simple inverted pendulum; and a single input multiple output underactuated nonlinear cart type inverted pendulum. Control of the systems with various control techniques are implemented satisfactorily both theoretically and experimentally. Results of simulations and experiments are compared with each other, and various inferences are made and recommendations for further studies are presented.
